How long of a barrel? Don't most f class use about 30" barrels?The 7/6.5PRC is starting to gain traction in the Fclass community as a competitive cartridge. It's basically a 284Walker/284Shehane with better brass. I have a reamer on order with JGS.
The typical accuracy nodes have been in the 2930ish area with Berger 180gr Hybrids....there is a higher node closer to 3k that's hard on brass. And a lower one in the mid to upper 2800's. This is with powders such as H4350/RL16/Rl23/N555.
