My plan as of yet is to do an auto in 6.5 and run it with my ultra 7 can. I'll be shooting either prime 130 or hornady 140 eld-m depending on what work gives me (so tuning ammo isn't an option). Would like it set up for a possible prs gun. Really eyeing the proof barrels (I have a certificate). Any recommendations on 22" vs 24"? I'm a little worried the longer 24 plus can, won't be as forgiving on shooting factory ammo because it's not as stiff. But the extra 2 inches would be nice for velocity. Any thoughts?
