I like the thought of a short action cartridge that can do that the 25-284 can do. I mean a true short action cartridge.I sure like my 25-284 , but something tells me the 25 cal neck down 6.5 PRC would be a screamer. Same 6.5 bushings dies with no other changes ,but bushings , med or long action.
I was real surprised to get great accuracy from my 25-284 with a 24" barrel and 133 Berger's at over 3200 fps with zero pressure signs. I'll admit 3170 gave me the place I liked the best but .3s at over 3200 with a 24" barrel is incredible IMO.I'm a 6.5 and 284 guy I have all the variants in those cal . I built a 25-284 1-8 twist last year , and am really impressed . I didn't even buy any dies , I used my 6.5-284 bushing dies with the proper bushing necking down 6.5-284 brass and my competition 284 win seat die too seat the bullets . I was surprised too get 3874 fps max and a average of 3860 with the 90 gr Hammer I have a old Speer reloading manual that has data for the 25-284 . I was comparing vel versus powder charge too the 25sst and I'm right with the sst pretty close . I also have several 6.5 prcs and have kicked around the idea of the 25 prc . All that's necessary is changing bushings , no other changes . Lapua Brass for both and your good too go . It seems the 25 PRC with the prc case design would be great , but if you where going for the heavies in that cal the med length action would be best . I built my 25-284 on a med action . I also have the 25-06 great cartridge but the AI would definitely be better . Regardless of the OPS decision they all are great cartridges and a lot of fun too try and get full potential out of them, my biggest problem is trying too pick what cartridge and rifle too hunt with every year , they all are great . Good luck on your 25 cal build.
I already have competition bushing dies for 6.5X284 and a lot of Lapua brass so would only need a Custom Reamer and already have .257 Throater so can go longer than a SAMMI Reamer for 25X284. Probably go LA (worry about cartridge length in Mag).View attachment 407019
I am rebarreling my 25-06 with a 1-7 shilen barrel. I decided to keep it an 06, since I already had everything to reload for it. Planning on trying retumbo, rl26, rl23 h1000 and 7977. I bought a couple of boxes of 133's last month. Here it is next to a 92 hammer hunter.
Until you have loaded for the 6.5prc you won't realize how strong and efficient that case design is . I have loaded some hot loads with Hornady brass the last few years in 2 different rifles of mine and haven't lost a primer pocket yet , that tells me it would be a awesome case for the 25 cal . I use too load for my 6.5-06 that I rebarreled too 6.5-284 and I was always smoking primer pockets , in my experience the 284 case and the 6.5 prc case are really strong in the webbing area of the case . 25 PRC would be awesome in my opinion.I was real surprised to get great accuracy from my 25-284 with a 24" barrel and 133 Berger's at over 3200 fps with zero pressure signs. I'll admit 3170 gave me the place I liked the best but .3s at over 3200 with a 24" barrel is incredible IMO.
