Help with 1/11.25 .308 barrel and ammo

[Bang4theBuck]

Actually, The 308 rifles that GA Precision build almost all have a 11.25" twist and they have lots of success with 175 SMKs and 178 Hornady match.

Just doesn't seem like it would work but proof is in the group sizes

So before the Amax went out the window I was running them in a 26 inch 308. Between the 2 there was always about 1 to 2 clicks more of elevation difference for the 178. I was actually running the 168 about 2800fps in that 26 inch barrel and the 178 seem to be about 25 FPS behind them. So I think the 168 to 180 is a real good load for the 308 when you look at retained energy and maximum distance. Generally I was a half inch at 100 and about 1moa at 1000. Wind was always and will always be a factor. Funny thing i sold the 308 and still have several loaded rounds for it. Been thinking about going back to that or a 7mm-08 for some rock/steal banging and getting rid of my 6.5 creed. It's just not capable of what I thought it could do interns of speed and distance when running a 140 or larger unless you using some ferry dust (RL26).

Run RL17 for maximum velocity (2886 no pressure and could go more) in your CM and use 140-143g bullets. Barnes Match Burners, ELD-m or ELD-x all work great to 1500. Realistically I wouldn't attempt to kill something beyond 500y with either a 6.5 or a 308 unless you make a good neck/head shot. Just my 2cents
