About half of my 125 cases had no resistance at all when I seated my rem primers last night. I haven' t looked at them close yet since I was packing for todays hunting trip. They did mic at .002-.003 more than the brass I started with. That is the head of the case. Could oversizing cause that combined with too hot of a load? Or were some just too hot? All these brass were loaded with 100 gr bullets from 22-24.5gr of AA2200.
We had a good night tonight and put two fairly large bucks on the ground with the 25/223. We were shooting the Hornady 100gr SP at 100yds and 135 yds at 2600 fps. The first was shot by my son through both shoulders and the bullet did not exit. It was fully mushroomed but I lost it tonight at the skinning shed. I was going to weigh it, but it looked fairly intact. The wound channel was good, but he did not drop right away. Followed with a second shot just to make sure he wasn't going anywhere, but he was going to go down anyway. The second was a good buck around 180lbs. I shot him offhand and shot a little far back. He went and bedded up about 150 yds in the woods and we anchored him with a neck shot. Figured it was a gut shot from the sound of the bullet impact. The first shot did exit at a 45 degree angle but it was through soft tissue. Second neck shot did not exit at 45 yds. This bullet is a good bullet if the shot is well placed. I think behind the shoulder shots will give complete penetration and pass throughs. I will be testing the Barnes x bullet tomorrow and if it is promising I will take it tomorrow and try it out on a deer. So far the score is three deer with the 25 in the last 6 days from 75 yds - 130yds. |

Re-post on the brass issue. After further review. looks like the Winchester brass I started with (once fired from an other than me source) mic's all over the place. So it probably warrants closer testing with before and after mic'ing of the brass at the bench. Never got to try the Barnes X bullets on Sat night. Didn't see anything that evening except Clemson getting stomped by Fla. State.

Quick question for 320pf or anyone who might know.
I shoot a lot of wildcats and am going to try out the 25x45 barrel by BHW. OK, we know the 45mm case is a few thousandths longer than the 25-223, 1.760 versus 1.700. Now, I have been shooting the .30 HRT for a long time (30-6.8 shortened to 1.610 inch after forming in a .30 Herrett die) and when we want to run a long bullet subsonic and suppressed, it is common practice to shorten the case so that the mouth is no longer past the full diameter of the bullet. Now, one would think that doing this could cause chamber erosion but it has not even though the subsonic loads with 240 SMKs are at high pressure. I think the amount of shortening was in the neighborhood of .010 to .015 inch which is a lot less than the .060 inch difference between the 25 x 45 and the 25 x 43 (25AR), but I do not recall exactly because I do not run my HRTs subsonic. I just know that people do that who do run it subsonic. For me, subsonic use is why the .338 Spectre was built. Anyway, applying the same 'trick' here, and the loads would not be subsonic but full tilt balls-to-the-wall loads, if one were to have a 25x45 chamber, such as BHW offers, and were to shorten the case to 1.700 inch as with the .25 AR so that one could run long bullets without seating past the full diameter portion of the bullet, does anyone see a problem doing this? The jump to lands would be the same, the throat would be the same, only there would be .060 unsupported neck area in front of the case mouth. With long bullets that is not going to cause misalignment of the bullet with the bore IMO and would give a little more neck, and a little more powder room for short lightweight bullets. Or do you, or anyone, think that .060 gap would eventually lead to chamber erosion? I do plan on shooting mostly the 80 gr. TTSX or the 85 gr. NBT and maybe some 100 gr. NBTs thrown in there for good measure, but I can also see some 75 gr. bullets being used once in a while. Or should I just buy a BHW .257 1:10 blank and let 320pf finish it for me, providing of course that he would do that? |

Lets just say that I know the 25/223 works and offers a greater selection of bullets you can use. I have no experience with the 25x45 but I do know that small amount does discount a few of the bullets I have used.

While I can't speak for the .25-.223 AR guys, the only problem(s) I see with that scenario is if a steady diet of really hot loads in the 1,000 plus rounds, it can cause throat erosion if the chamber is cut for the longer case neck...Two, you would likely need to put a crimp on the case mouth to help keep the projectile aligned and to help get consistent start pressures and a more consistent burn, etc. Good Luck. |

Hi Big-Bore,
First! Yes to your question if you buy a BHW 0.257 1:10 blank I can finish it to any length and profile that you like. Now that is out of the way. There are three issues with cutting the brass too short relative to the chamber length. Two issues have already been pointed out by Dr69er in the about post. However, just to enumerate on these a bit, by trimming the brass back by 0.06" (2mm) you will not realize the full accuracy potential of your barrel. The third issue can be much more serious and can result in a dangerous condition. Chambers are cut such that there is a slight step (0.009-to-0.01") in the neck area to account for the thickness of the brass in the neck part of the case. If you constantly have to trim your brass 0.060" (2mm) short copper jacket shavings can build up in the throat area, resulting in an constriction in the throat area and cause excess/high pressure. If you have any questions PM me and we can work on getting you a barrel. 320pf P.S. Somewhere earlier in this post I made a list of bullets that will not work well in the 25x45mm because the ogive is too long relative to the magazine length (2.255") restrictions. I can repost the list if people want to see the numbers/measurements. |

Thank you for all your replies.
I know that when you shoot .458 Win. in .458 Lott excessively that there have been reports of chamber erosion and then Lott brass sticking, but that is in the neighborhood of 1/2 inch shorter case. But I was not sure that would happen with only .06 inch since it does not happen with other relatively high pressure rounds like the .45Colt/.454C, .44 Special/.44 Magnum, and the aforementioned .30 HRT. Freedom Arms states in their manual not to shoot .45 Colt in their .454C chambers for exactly the reasons 320pf mentioned, build up in front of the short case if not removed completely can form a 'pinch' area when you shoot the longer case and there is no room for the case to expand to release the bullet, and that ain't good! Those areas do not concern me because I am well aware of them, but the one that is a deal breaker for me is the degradation of accuracy. I knew that the .458 Win is not as accurate in the Lott chamber because of the extra 1/2 inch jump but have not seen accuracy fall off in the .45 Colt/.454C or the .44S/.44M, but then we are talking short ranges too and as I mentioned, I have not done the short case in the .30 HRT. Any reduction in accuracy in a longer range round like the .25-.223 is really defeating the purpose of the cartridge. So, thank you everyone for answering my questions and clearing that up. I have bought blanks from BHW before in .308 and .224 diameters so if they will sell me a blank in .257 then I will be contacting you, .320pf, in a month or two. Past experience with BHW is that when you order, regardless of the "It will ship next Monday" statement, you really will not see it for about 8-12 weeks. But the wait has been worth it. Those darned barrels SHOOT! I have another wildcat build in the final stages now (chambering and profiling) so when that is done in a couple of weeks, on to the .25-.223 build. One cannot have too many wildcats in the barn, can one? |

We dropped a yearling doe Friday night for meat. Can't tell you much about the performance of the Hornady 100 grainers because my 9yr old made a slightly off shot and caught the mid- section. We recovered the deer, but she was pretty messed up. I will say we have shot four and recovered them all. He shoots this rifle with great ease. No kick or recoil. Highly recommend it for young children.

Well this thread has definitely changed my mind on my next rifle. I think i will be doing a 20 inch. What gas system seems to be the winner for a 20 inch? Also, what gas block are most people using? Will a standard gas block fit on these barrels?

Hi nootay,
Welcome aboard. All of the 20-inch barrels that have been made run a standard rifle length gas system. The gas block depends of the barrel profild. Other than the barrel, standard AR parts are used throughout the rifle. 320pf |

Planning on building a Rem 700 in 25-45 Sharps. I guess I'm going to have to purchase a reamer.
I like the idea of having a bolt action and a AR based weapon chambered in the same cartridge. Did that with the 6.8 SPC, it did have a few draw backs concerning cartridge OAL. Had a reamer and dies made for the .25-204 last year, never did anything with it and sold them before committing to a build. Now I'm running a 6x47 Rem in a Rem 700. I've taken a lot of deer with a .25 caliber from the .25-35 Win to a 25 WSSM. Love the caliber. This thread has been excellent and have been following it for months. I've got a few bullet test pics I'll post. Thanks for all the great post ! |

Here's a few bullet pic's some might find interesting.
Bullets test fired into water jugs. Impact velocities 2,000 - 2,200 fps Barnes 80 grain TTSX with tips removed to aid in keeping OAL of the cartridge to minimum. http://i31.photobucket.com/albums/c365/wheeler_/25ca_zps307fc12d.jpg It would be nice if Barnes or Nosler would offer a bullet designed for the 25-45 based cartridge. Notice how the 6.8 SPC based bullets have a larger cavity that aids in expansion. http://i31.photobucket.com/albums/c365/wheeler_/ad9dd77e-148f-4069-a38c-893c8cb7d29a_zps1ddadf0f.jpg Killed several deer with the Sierra 90 grain Gameking JHPBT out of a short barreled .257 Roberts (2,980 fps). Never found anything other than jacket fragments inside the chest cavity. http://i31.photobucket.com/albums/c365/wheeler_/DSC01344_002_002.jpg A few jug tested Gameking's http://i31.photobucket.com/albums/c365/wheeler_/e490b95c-ef80-4557-90a5-27175aea59e5_zpsedee0118.jpg http://i31.photobucket.com/albums/c365/wheeler_/d2d08213-5bd9-46f6-97b0-17adadf6280c_zps9a8f362b.jpg This Gameking came unglued at 2,200 fps impact, water jugs are hard on hollow points... http://i31.photobucket.com/albums/c365/wheeler_/DSC05617_zps33bc11f8.jpg I've been told the Remington .25 cal 100 grain SP was designed for the 25-06. I believe it after impact at 2,000 fps into the water filled jugs..... http://i31.photobucket.com/albums/c365/wheeler_/DSC05619_zpscba31ec9.jpg The Remington 117 grain Round Nose soft point opens nicely at 2,000 fps impact. http://i31.photobucket.com/albums/c365/wheeler_/f1fb52ae-29f2-4158-a59f-2797df2af7d9_zpsc3c7a864.jpg Never have used the Nosler 85 grain Ballistic Tip, seems this would be a great choice in the 25-223. Nice thick base, similar to the 100 gr.

Hi Nootay, I assume that you are referring to putting a mid-length gas system on a 20-inch barrel. Basically, a mid-length gas system will have the bolt opening too early in the firing cycle. So you will have to load to lower pressures and will not realize the full velocity potential of the cartridge. I have done the timing calculations and I come up with what they have for the 5.56. A 14-inch length barrel (M4) will operate best with a carbine length gas system. The mid-length gas system is optimum for a 16.5-inch barrel and the rifle length gas system for a 20-inch barrel. 320pf |

I have read that people are using the .25 WSSM Hornady seat die for seating; can't you use them for crimping also? I use several of the Hornady seat dies for my wildcats and they are obviously not specifically designed to work with the caliber I am loading, but they have a crimp shoulder and do allow you to crimp if you so desire. If you feel you need to crimp then the Hornady seat die will get you through until you can get the Lee die made, which IMO is far superior than any built in crimp shoulder or taper crimp.

chrome i can attest to the sheer violence of the 85NBT bullets. they will damn near cut groundhogs in half at 200yds. What they do to rabbits is amazing.
I have played with almost all the LW 25cal bullets ive been able to get from 60-100gr i mainly shoot 75gr HP and 85NBTs. I have almost 2.5k rounds through my rifle now. Ive shot it from 0-635yds in matches and have killed over 80 groundhogs with it. I love it, although... I had become disappointed in my 25ar over the past few months while shooting some precision matches so expect me to have some more data and write ups this coming winter. I am going to sit down and tear my rifle apart rebuild it and restart load work ups on the bullets i have in stock. I may even bug someone for a 20" barrel

Just to foreshadow a little bit, I have been seriously working on my 25. Experimenting with low mass carrier, adjustable gas system, modified magazines, different bullets, Lt32 powder, new AA2200 charges, 2.30 and greater COAL lengths, etc. If 320PF would make a new reamer (hint hint) with a longer throat, this cartridge can be pushed to a new limit. When I finish up some more experiments I will post the findings.

If there is some demand, I can have a throat reamer made so one could extend the throat on existing barrels or do a two step cut on new barrels for making chambers with a longer throat. I know that there are a few bullets that could use a slightly longer throat. The Sierra 90g GK comes to mind. |

Hi scatterbrains, I have shot the 25-223Ar in several 30-gun matches and had the best results on the long range targets with the heavier bullets. Gusting winds really causes grief, especially in the afternoon when the winds tend to really kick up. That is why I like to shoot the long stages in the morning when the wind is relatively calm. But you do not always draw that shooting time. Below is a comparison of the wind drift with a 90° 10 mph cross wind at 300 yards.
I have had the best results with the 90 g Sierra BK and the 100 g Sierra MK. I tried the 70 g Sierra BK at one match and I really sucked at the 300 yrd steel while in previous matches on same stage I had done well with the 90 g and 100 g Sierra bullets. I have not tried the 85 g Nosler BT but they should perform similar to the 90 g Sierra BK. You just gotta love high B.C. and high velocity. |

Yeah ive been running the 90sbk and 85nbt. I honestly got frustrated with the rifle function than the ballistics something went wrong with the rifle at least 2x every match.
Thats the real reason so a full teardown will be done this winter. No i am shooting a 243win in the matches i must say i loove it my new favorite gun in any form as of late. How are the 20" barrels treating you? |

Hey all. I came across some 90 gr Sierra HPBT game kings and some 87 gr Speer "TNT" HP bullets. I have been combing through this thread and have gone cross eyed, lol. I am just gonna come out and ask for and data you all might have come up with for these bullets/ bullet weights. I have 2200, 2230, Reloader 7, and Benchmark. I would appreciate any data you have to help me save some time and components. Thanks all!!

I haved used the 90 GK a lot and many 87gr bullets, just not the TnT. I would suggest using 2200 starting at 23 and working your way up. 2230 and bnchmrk are a little slow for this cartridge based on mine and others experience. RE7 while having the right burn rate, is such a large powder that it quickly fills up the case leading to compressed charges. I used to advocate RE7, but I have been experimenting a lot recently and have concluded it is just too large; a .5gr charge increase can go from safe to popping primers because it is too compressed, even at my 2.30" seating length.

Finally found one I could shoot. 1 shot ..70 yds...DRT. Went down instantly. Bullet penetrated behind the right shoulder and exited through the front left. Had about a quarter size exit wound. I would say the impact broke the spine since he went down back feet first.
This is a Hornady SP 100gr bullet over AA2200. It is running about 2600-2640 fps out of a 16" barrel. This makes number 6 with this rifle this year.

I think it is 24.5 gr of AA2200, but I will have to check to make sure. The Sierras and the Speers generated a little too much pressure when it was warmer to keep them at 24.5gr, but the Hornadys seemed to be fine.

I think it is 24.5 gr of AA2200, but I will have to check to make sure. The Sierras and the Speers generated a little too much pressure when it was warmer to keep them at 24.5gr, but the Hornadys seemed to be fine. That sounds right on with my experience. The Sierras were maxed at 24.2 for me. |

rdc,
I use the Sierra 90g HPBT. Love them. I use AA2200 with them. I walked up from 22.5g I believe. I found the best grouping at 24.2 - 24.5g I never went above 24.5. I don't have the chrono data off hand, but can post it after hunting season. I have also run Nosler 85g bullets with RE7. I agree with scatterbrains that it is too large and does compress. Once my RE7 is gone, I am going to try the aa2200 or look for another alternative. |

It looks like the view is towards the front of the deer so is the bullet travel right to left as you described in your post? It looks like the bullet broke two ribs and the spine. Classic 25 cal 100g bullet* performance. * See Altair's ballistic gel tests earlier in this post. I think that some of the photos have been moved but there are still some up on page 34 of this post. |

Had the old nutless Savage out today...put a 4-12x Nikon coyote scope on it.....not my favorite but it works.
Got it zero'ed at 100 with 85gr Nosler Ballistic tips moving just under 3000fps. Punched the numbers into Nikons spot on program and shot 200,300,400, and 500 with it, pretty close had to change a couple hold points but looking good. Now I need to get out and do some calling I guess. I did just get another Savage in 204, model 11 with a detachable mag, its a very accurate little rifle but I just cant warm up to that round for some reason. Thinking it might need rebarreled into a 25-223 in a light weight configuration. Wouldn't mind a 6TCU to go with my contender though either......hmmm |

I was surprised it clipped the backbone as low as the entry hole was behind the shoulder. I was pleased with the SP's performance. Shot placement is the key from what I see, as this round will not overpower the target. However, with correct shot placement the performance is more than adequate. |

Looking at the past posts from Altair in regards to the gel tests, I gather the 100gr Hornday SP performed in line with his tests of other 100gr bullets. It did look like it disrupted around 5-6" of tissue from 4-6" inside the chest cavity. That would explain the clipped backbone. Hopefully I will get to try it out on a hog this weekend. Lookin' for pork! Need some Thanksgiving BBQ.

Well I finally got a chance to try one of the loads that I worked up with the new Accurate powder LT-32, a favorite powder with the Bench Rest shooters. Accurate lists the burn rate for LT-32 is between 1680 and 2200. It is a fine-grained extruded powder and meters very well.
I worked up some loads with the Hornaday 75 g VMAX bullets. I shot a latter using a Burris TAC30 (Note: the center dot in this scope is 2/3 mil [2.4" @ 100 yards]). starting at 25.5 g to 26.5 g in 0.5 g steps. All of the groups held 1-inch or less. Here are the results.
LT-32 does not seem to be a barn burner but all of the loads I tried shot tight groups. I think that I am going to settle in on the Hornaday 75 VMAX for my varmint/plinker load. |

What headspace gauge should I use for this build? A regular 223 I'm guessing?

also, im in the process of ordering a reamer from pacific tool and gauge. They have a reamer on file for 25-223. When i gave the dimensions to dave a ch4d, his reply was:
"Your drawing is -.0018" on headspace dimension & +.0018 on shoulder diameter. but with a SAAMI tolerance of .0080" on all diameters I don't see it being a problem" Im pretty sure pacific tool can do special orders. Is .0018 worth getting a special reamer made? |

320pf,
I never asked, but what is the twist for the 16.5" barrel I ordered from you? People are asking me, and I am drawing a blank. |
