I was under the impression that a Redding Type-S 223 bushing die could not be used for a 25 as the neck hole is too small. They, Redding, told me it would take a special order die. Have they changed? Is anyone using that set up here?

I am using the redding 223 neck bushing die, without any neck bushing. :)
I'm using a 25 cal sized decapper and all is well. The place where the bushing sizer goes, sizes the neck down a fair bit, but then on the way out it puts the neck at the right size. it works the brass a bit more than it should, but it's doable for cheaper than the CH4 set. |

Nice gun DK223.
Are you willing to share the build information, or if it is in this forum, the page number? |

It starts back on page 46. I have several post on this right in this thread. P-dog, gophers, antelope, steel....lots of my info here.

Nice looking rifle.
I understand that trimming to the 25-223 length is a bit a pain (certainly my least favorite part of brass prep) but being able to use a much broader spectrum of .257 bullets makes the trade-off worth it to many for the AR-15 platform, where we're limited to a cartridge overall length of 2.26". If I were working with something else which allowed a longer cartridge overall length, it's a little different story. Keep us posted. |

I went with the 25x45 chamber for the simple ease of not having to trim down the brass to the 25/223 length. Using the RCBS dies. Worked up some loads of AA2200. Got it on paper at 100yds. But the wind has been so bad here to get a real good accuracy test out in the desert. Best I could do with the wind doing what it does best is about 2in. Will re-engage when I get back sometime in Nov. Didn't draw a deer tag this year, so I will have plenty of time to fine tune the load. The wife has claimed the rifle as "hers". Which is ok. You just know what that means. Went with the midlength 16" stainless barrel from BHW. PSA lower. Anderson upper. UTG pro series hand guard. Running an H buffer. Wife agrees, it recoils less than a 5.56 Weaver scopes have always served me well, so I used what I know. Very nice pic of the Rifle, looks sharp, BHW makes some nice barrels for the money...Good luck. https://fs4nzg.dm1.livefilestore.com/y2ptjACdhroW7_eoVJRX7ZxEwyNJ7DhrqAuD2Kdw5sXTFTTew6ZVoTUn9xcGXyGQORTVRwbr5QD3oajCToNZ_cUkGZKtgyVnUtbY9Sqke0k0VA/25x45.jpeg?psid=1 View Quote Very nice pic of the Rifle, looks sharp, BHW makes some nice barrels for the money...Good luck. |

75 pages worth of info and I'm the only one updating it? What the heck. View Quote The end of last month made it an even four years ago that this thread was started. As for myself, I found my loads in the first year and have just been enjoying the rifle. As mentioned earlier, trimming the brass may be a pain but it really isn't that bad. Every now and then I'll sit down and do a large batch in one day and I'm set to go. Just the fact that you are posting the results of shooting at p'dogs at 900 yds.+ shows the versatility of this cartridge. I was looking for a light weight, easy to carry carbine capable of taking our smallish (125-150 lbs.) mountain whitetails up to ranges of 200 yds. The 25/223 has worked well for my purposes. Every cartridge has its limitation and I take my hat off to you; because I think you found it. But if you are enjoying the process I would say the efforts are worth it. |

I will play along! Who used the reamer and what was the outcome? I think it was going to reduce the pressures in the round by allowing us to seat further out? Inquiring minds want to know.

Hi dk223,
You might want to give the Sierra 90 g BlitzKings a try. They have a better B.C. so they will have about 20 inches less wind drift and aabout 100 fps more velocity out at ~900 yds. thank the Noslers. I know from reloading the 90 g Sierra that the gliding metal near the tips is very thin. This might make enough difference that the little buggers do not crawl off. The Sierra 90 g BK are pretty much my go to bullet now. I would like to try them out on some pig and deer just to see how they do on the larger game. Nosler 85 g Ballistic Tip 3000 fps at the barrel (B.C.= 0.329)
Sierra 95 g BlitzKing 2950 at the barrel (B.C. variable*)
* .388 @ 3100 fps and above .375 between 2900 and 3100 fps .345 between 2400 and 2900 fps .330 @ 2400 fps and below |

I have been following this tread for a bit, The plan is something in the AR platform for hogs, yotes and possibly deer. I was very pleased to see this caliber has already been played with because I am a big 25 caliber fan. I was about to take the plunge and get a 25x45 barrel for a build. The only reason I picked this one over the 25-223 is because I already have a bolt gun in the 25x45 and don't want to worry about mixing brass. I called to place an order and was told that the twist rate on the web site was incorrect, the web site listed the barrels as a 10 twist, however I was informed the barrels are actually 9 twist, which I thought was odd for an AR because I did not think anyone is shooting many bullets heavier then 100 gr. and these barrels are made specifically for the AR-15.
I want to shoot between 75 and 100 gr. bullets. Most will likely be 87's and 100's. Will this twist rate effect the lighter bullets? Does anyone have any experience with a 9 and 10 twist with 75 and 87 gr. bullets. The plan was a 20 inch barrel, LTR. Anyone have a 24x45 reamer if I go a different route? |

View Quote I believe the only difference between the .25-223 and the .25x45 is the trim length. Hopefully someone more familiar with the .25x45 can confirm or correct this. The reason for the shorter trim length in the .25-223 is the magazine limitation in the AR15 to approximately 2.25" COAL (some magazines can stretch this a small amount out to about 2.30"). My guess is that 100gr bullets loaded in a .25x45 case will be too long to use in an AR magazine. As for the twist rate, I believe mine are 1:10 but 1:9 certainly wouldn't bother me in any way. Mine have stabilized everything I've tried through them up to 100gr. |

HI Scatterbrains
If you can get your hands on the Sierra 90g BK I think you will be very please with how they buck the cross winds compared to the noslers. This bullet shortage really sucks. To the rest of the group I have an order for two 14.5 inch barrels. This will leave me with two 12.5 cut-offs. Would any of you be interested in having one of these cut-offs cut into a barrel? Remember these would need the appropriate paper work for a SBR (Short Barreled Rifle) or pistol 320pf Originally Posted By scatterbrains:

Hi All,
I now have all fixtures for the throat reamer. I updated/cut new throat on two barrels and one case gauge and tonight. The makes the job pretty easy. The new throat is 0.750" longer than the original (0.280") throat. This is similar to the throat length of the 6.8 Spec II chamber. This should be the optimum throat for bullets with an overall length of ~1 ". This would include bullets like the Sierra 90 g GK and BK, 100 g GK, and ProHunter; Nosler 85 and 100 g Ballistic Tips and 100 g Partitions; the Barnes 80g TTSX; Hornady 100g InterLock; and the Speer 100g BT, and HotCor. Pictures and tests to follow 320pf. |

Thats good to hear brent, cant wait to hear results.
On the results note i was able to get out and get some work done on the 75gr bullets i have on hand, sierra 75gr HP, Hornady 75gr HP, and 75gr Vmax bullets. All loads are R&P brass cci450 primers and H335 powder, cases sized to 1.454" I had already done some initial load work up in the past so i had a good starting point. I loaded up 5 of each at 26.8, 27, and 27.2gr. All loads were shot prone with bipod and rear bag. 75gr hornady HP 2.230" OAL 26.8gr=.908" grp/ 27gr=.922" grp/ 27.2gr=1.507"(pulled the 1 shot to the left) AVG=1.12"--I have settled on 27gr as my load for this bullet. 75gr vmax 2.250" OAL 26.8=1.9"/ 27=1.3"/ 27.2=1.3" (Will be reshooting these again) AVG=1.5" 75gr sierra HP #1600 2.225"OAL 26.8=1.25"/ 27=1.7" /27.2=1.35" (Will be reshooting these again) AVG=1.4" I could probably just settle on 27gr for every 75gr bullet and be GTG but i would like to get them all below 1moa@100yds. It should be more than doable if i can not get it the way LOL. I have no chrono data as my chronograph had stopped a bullet a month ago or so doing 4000fps So no velocity data will be had. I will update this when i have some more time to really break it down. I will say from best to worst where the Horn HP, then vmax, and last were the sierras. All loads fell below 2" at 100yd for 5rnd groups, but the 75gr HP avg. below 1" the vmax were avg @ 1.5" and the sierras hovered around 1.5". I am reshooting the sierra loads to see if it was me. (i truly hate shooting paper nowadays ) Hmmm guess my memory was shotty seems the loads all shot below 1.5" Either way this is a good point if you guys are interested in playing with the lighter bullets. I have some 70gr BK i havent tried but will in the near future |

There have been several inquires about how the 223-25AR performs in a 12.5" barrel. As far as I know, to date a the 223-25AR in a 12.5" barrel has not been done yet. Since I do not live in an AR-15 pistol friendly state I have not done one of these. Although I sure would like to try one.
Ballistic modeling, which matches my 16.5" barrels pretty well, suggest that a 100 gr Sierra GK will drop from 2550-2600 fps (~1450-1500 ft-lbs) in a 16.5" to about 2430 to 2460 fps (~1390-1420 ft-lbs) in the 12.5" barrel. The 87 gr Speer load will drop from 2780-2812 fps (~1490-1530 ft-lbs) in a 16.5" to about 2650 to 2680 fps (~1350-1380 ft-lbs) in the 12.5" barrel. The Horn. 75 gr VMAX will drop from 2980-3000 fps (~1470-1500 ft-lbs) in a 16.5" to about 2830 to 2860 fps (~1340-1360 ft-lbs) in the 12.5" barrel. So the big question is who is going to be the first to break new ground here? 320pf Originally Posted By 320pf:

Just a quick question, and I think I already know the answer, but a .25-.223 will not chamber in a standard 223 Rem chambered upper, right? There should be no possibility of a KB! from mischambering, correct?

Some observations:
I got my barrels back with the new reamed chamber from 320PF, and while I haven't been able to escape to shoot yet, I can say a couple things. First, the work looks perfect. I examined the chamber with a surefire and it looks perfectly clean, so 320 did a good job there. Second, my 2.30 90 gr game king load which was hitting the lands before no longer does, which was the whole point in the new chamber. I am very excited to get behind the chrony and see the effects of the new chamber. I have high expectations. Lastly, HK Marine mags allow a COAL of 2.301 with no modifications. They are a little pricey, but I was able to get some off the EE for 35 dollars a piece. I believe the combination of the 2.3 length, using HK mags, coupled with the new chamber is going to bring this cartridge to its full potential. I hope to get out sometime in the week, but I have a lot going on right now. |

Wow. The 300 BLK case is so short I can see that happening. I just dropped a 25 dummy I made into a 223 and it wouldn't even lock up the bolt.

I hope to get out sometime in the week, but I have a lot going on right now. Please keep us informed. Very interested in the report. My brother went out yesterday and shot some of our old standard loads to check for accuracy, and there was zero accuracy degradation post chamber reaming, it shot great as it always has. For a pressure test he loaded up five rounds at 25.2 of 2200 behind a 100gr interlock at 2.30 (one grain more than our old standard 2.26 load). Perfect function with the HK mag, good accuracy (around MOA, no bench just 'truck bed prone') but was showing pressure signs, and his last shot popped a primer so it is too hot. No chrony though. He will be working up from 24.5 hoping to get to 25.0. So far we are both happy with the results. I will do my best to get out in the next week or two for chrony testing. |

Is anyone using a Giraud trimmer for this brass and if so can the normal 223 shell holder be used? Thinking about getting one and trying to figure out what holders I will need.

View Quote The Giraurd looks similar to the Gracey I have. The holders fit closely on the necks to avoid chatter and tearing. I suspect the Giraurd will be the same way. I can't put a 6X45 case in my 223 holder. Greg |

So I probably would have to get a blank shellholder and have it cut with the reamer to fit if I went that route. Might be worth it. Prepping brass is my least favorite thing. Wonder if Geraud would take a 223 shellholder and put a 25 cal neck in it. I might have to ask if that is possible.
Thanks 320 for the pic of the Forester. I am changing my reloading style and looking for more efficient ways of doing things. Time is getting smaller and smaller for things I used to consider a neccesity. |
