6 PRC reloading

[Titanmoose]

I’m awaiting my PBB 6 PRC barrel. Should be done in a couple weeks or so. 18” .750” taperless, 7.5 twist, diamond fluting. I had them add .040” freebore, so I’ll have a total of .180” FB.

I went with a SA (Atlas lite) so I was partially concerned that mag length / jump with above .140 would be too much for the 105-108’s. Or be hampered by OAL if you went with a tipped round.

I also know nothing so I wasn’t brave enough to add FB initially good thing barrels are cheap

I ordered the same but in 20". What bullet are you planning to shoot? I was planning to shoot 108eldm will the standard .140fb be enough?

I suspect it is. I don’t know for certain. You can always add FB.

You’ll be fine! You might be seated .020” deeper than optimal, but realistically your velocity won’t be much difference. I don’t think it’s enough to lose any sleep over.

I went out earlier today to try out some 1x fired brass to see if I could get my SD/ES down from unfired. I'm shooting 108 Elite Hunters and had 5ea at 59, 59.5, and 60 grains N565 loaded 25k off. My barrel must have sped up because velocities are significantly higher than what I had been seeing. Unfortunately my top charges didn't have the accuracy to pursuit any further. Rifle has a 20" ACE SP3 and TBAC Ultra 5 for reference -

59gr - 3,163 avg, 18.2 ES, 7.3 SD ~1 MOA
59.5 - 3,203 avg, 20.6 ES, 7.7 SD ~1.5+ MOA
60 - 3,246 avg, 17.5 ES, 6.2 SD ~1.3 MOA - slight sticky bolt

I think I'm going to load 5 each 58.5 and 59 this weekend, pick the best of the two and just start shooting. I'm not sure if this Ace barrel isn't a big fan of these Elite Hunters or something but I may give some 108 eld-m a try at some point once I've had a chance to shoot at distance.
