I didn't pick the extension, 320pf did, and it was an M4 style extension. I actually don't know why anyone still makes non M4 extensions because you can use an M4 feed ramp extension on a non-M4 feed ramp upper but you cannot use a non-M4 feed ramp extension on an M4 feed ramp upper. I think he made the right choice. With the M4 extension you can mount this barrel to any exsisting AR upper without modification. |

I actually shot these in Oct and posted them on Quarterbore.net. It seems that this load got lost in the "quotes". Sorry.

In the end, the weight difference was minimal and I didn't have to worry about the barrel being too thin. I wanted something light and handy but not fragile. I'm happy with how the rifle balances with this barrel. I have about 50 cases ready to accept bullets and powder so I should get some rounds through it soon. There hasn't been much load development with IMR 3031 (which somebody mentioned ws listed as an ideal powder for this case based on computer modeling) so I think that's what I'm gonna start with to see what I get. I'll be sure to post the data when I do. |

I have thought about making a feather weight barrel in this caliber, but I have not had the time to sit down and draw it up. Also, before I actually cut any metal, I would like to do a bit more research.

I'll be sure to post the data when I do. Somewhere along the line someone mentioned 24.5gr of IMR 3031 as being a max load with a 90gr bullet. Given this info, I decided I would start with 22.0gr of 3031 under a 100gr Hornady Spire Point (from the blem bullets sale). I dumped 22.0 grains in and there wasn't room for the 100gr bullet. Not even close. I wasn't comfortable starting with a compressed load so I ditched the 3031 altogether. Instead I looked at Ramshot TAC. I've had great luck with this powder in 5.56 and it has a very similar burn rate to H335 which seems to be giving good results. I started at 22.0gr and there was plenty of volume left for the longer 100gr bullet. With any luck I'll have time to shoot them tomorrow and see how it performs. |

Well, yesterday didn't go as planned. It rained all day so I didn't get to shoot. To add to that, I blew up a radiator in my plow truck and my XBox 360 took a shit on me (red ring of death).
Well, I did get to fire those rounds today at least. Here's what I got: 25-223, 16" bbl, 100gr Hornady SP, TAC powder 22.0gr.........2100fps 22.5gr.........2115fps 23.0gr.........2175fps I didn't get any pressure signs so I'll bump the loads a bit. I'm not even up to my 5.56 pressure loads and I did that intentionally, I didn't have a starting point and I wanted to err on the side of caution. From what I've seen so far, though, I suspect TAC won't pick up speed fast enough to compete with other powders that have been tested. Too bad, since it is my go to powder for .223 and it would have been nice to be able to stock just the one for both applications. I'll try it anyway though. This is too small a sample size (5 shot strings) to make any conclusions just yet. |

Just a quick question....I use Lee case trimmers as thats what I have always used for years and I like them. But since there are no pilots from Lee for this case and it needs to be cut back just a little more than a standard 6x45 or 5.56 case I was looking for suggestions on a trimmer to use.
Also as this is going to be a coyote rig, I plan to shoot 70gr Sierras Blitzkings or 75gr Vmax's I was interested if anyone has done any load work with these? I would really love to 87gr Speer TNTs but just do not think you can push the Speers fast enough down the tube accurately for it to be effective out to 300m. Thanks |

Thanks Try the Lyman Universal Case Trimmer (Made In USA) @ Cabelas ,Item IK-21085 $59.99 I've used it w/ the Power Adaptor (will work with most power hand drill or power srcew driver) (Item # IK-210966, $19.99) works great. http://www.cabelas.com/product/Lyman-Universal174-Case-Trimmer/731718.uts http://www.cabelas.com/product/Lyman-Universal174-Case-Trimmer-Power-Adapter/731756.uts You can try the: (Standard reloading disclaimer, start low then work your way up) Hornady .257 caliber 75gr V-Max @ 2.260" COL w/ H4198 powder @ starting load of 20.0 grs. for a estimated velocity of 2,619 fps. Maximum Load is 22.6 grs of H4198 @ a estimated velocity of 2,920 fps. @ 50,000 CUP w/ a 20" bbl. Thanks for the info on the Lyman...looks like it will do what I need. Since I have been playing with my 6x45 quite a bit, I am thinking a .257, 70gr Blitz King using H335, XBR 8208, BCL2, or X-Terminator might get me the accuracy I need and the speed I want. We will see...... |

Using the Sierra # 1600 .257 cal. 75gr (HP-V), Max Load is 27.1 grs of X-Terminator @ 2.260" COL w/ a estimated velocity of 2,969 fps @ 50,000 CUP pressure.
It unfortunatly dosen't list the 70gr. Sierra Bitz King on the chart. |

I've done it 2 different ways and they both seem to work about the same. My first method was to take and extra .223 pilot I had and just trim it a bit shorter. Trim the .223 case, then resize it in the .25-223 die. Other method was to buy a .25 WSSM pilot. It's actually just a bit too short so I ended up using some JB weld to lock the pilot in place without being screwed all the way in. |

Color me quite interested in this, which has the sincere potential to be my first wildcat cartridge as well :D
What's the heaviest bullet ya'll have successfully loaded in this? Highest b/c? Anticipated use is a paper puncher (maybe predator/varmit hunting later on), beyond 400 yards. |

Also looking at X-Terminator as I am trying to maximize the cartridge for an SBR and I believe X has a slightly higher burn rate. I have renewed hope for TAC in this caliber. I looked through my Hornady reloading manual and for .223 the listed TAC loads were very similar and sometimes a bit higher than those listed for H335. According to information posted earlier in this thread, H335 had good results with up to 26.1gr with a 100gr bullet. I think perhaps I started too low with the TAC when I picked 22.0gr but I wanted to err on the safe side. Interestingly the rifle cycled without any problems using TAC even at those low charges and with the small gas port the barrel was shipped with. If nothing else, it should cycle very reliably when the pressure and speed come up. I'll post results as I get them. I'm off all next week so I should have some time to play around more. |

Anticipated use is a paper puncher (maybe predator/varmit hunting later on), beyond 400 yards. 100 gr bullet is about the limit, and even some of them (like the Ballistic Tip) are too long. I like my .25-223, but if you are just punching paper and maybe varmints I don't see much advantage over the .223, especially beyond 400 yards. |

Mine cycles just fine with the small gas port as well. I ordered a variety of wire size drill bits thinking I would have to open the gas port up, but so far it hasn't been necessary. I've been shooting mostly H335 lately. Oh and I just got an e-mail today that my chrono has been shipped. Merry Christmas to me!!!! |

Unfortunately my luck during deer season was limited. I got two deer but both were during times I had a .308 and not the 25/223. Anytime I was in the situation where I could have a 200 yd. plus shot I took the .308 instead of the AR.
However, I have faith in the ability of a 100 gr. bullet going 2500 fps. That is a 33% increase in mass over my 75 gr. bullets in the .223. I'll go back to trying to see what it will do on the coyotes around here. I should be able to run several load test this weekend to see the advantage of the H335 over the H322. I will say that knowing the rifle will put every shot in the same spot day after day, time after time has a true advantage over a few extra fps. |

It also estimated about 100fps faster than I actually got with 24.0gr (2260 vs 2350). I'm using Lake City brass too so it isn't thin bass. Regardless, thanks for running that for me. At least I'm in the ballpark according to your software. |

The program does tend to be on the "safe end" of the scale...and its does note that case veriation can be up to 1 grain of powder, so it does go with the lower scale. Adjusted, it shows as 25.2 grs @ Max Case Capacity for TAC w/ H 100gr SP. |

I have a question for you guys that already have yours......What are your groupings looking like?? Since I plan to use this as a predator gun I have a thing that if any rifle I own won't group 1" or under its out the door it goes. Of course I understand that load work up is a must and I spend lots of time working up predator hunting loads. So I care more about terminal performance than paper shooting but accuracy is a must as a base to start with. That is to say I look for the load that gives me the best of everything I can get out of it to ranges out to 300m using lighter bullets. Anything past that and I just break out my 25-06 heavy barrel for long range predator work.

Hi All,
I hope that you all had a successful hunting season(s). I am thinking of looking into/putting a group buy together for 25-223Ar dies. How many of you would be interested in participating? I am hoping that if we contact CH4D with a large order, they would bump up the priority. If that does not seem to be a viable option then we can look into getting another vendor. I am also putting another barrel run together. I have been contacted by about 4-5 people that are interested in getting set up with a barrel. So contact me if you are interested. 320pf |

AND I STILL AM! After that first one hundred rounds or so it just fell together. Most loads I have tried have been efforts to improve velocity and I've hit several highly accurate loads. I'm trying a few loads tomorrow but I'll go with accuracy over velocity any day. A few more days and my playing will be over. Once I find the right combination I'll re-test it for the next few trips to the range and then load up 500 plus rounds to play with. |

Just a short range report.
Speer 100 gr. bullet, Win. Small Rifle Primer, Formed LC brass, 16" barrel Using the H335 I had loads working my way up to 26.0 grains. At that point I was getting an average velocity of 2533 fps. Now I'll start loading in 1/10th grains increments and see what happens. With everything I've tried so far I am getting the idea that with a 100 gr. bullet you are going to end up somewhere between 2500 and 2600 at best. I'll be happy with the 2500 plus and fine tune for accuracy. The H332 and H335 seems to work out the best for me with H335 having a sllight edge in velocity. Function was 100% I have a Leupold 1-4 scope on the rifle now since I just went through our deer season but will put something with a little more power on it to try to work out the most accurate load. Once that is done I'll go back to the 1-4 just because it is so handy. |
