I've read an awful lot about 6mm PPC, recently reading a thread which stated that the really competative shooters shoot rather light bullets in the 60gr to 64gr area. I'm curious as to why Sako might have picked 70gr bullets for their factory loaded cartridges. I owned a Vixen Hunter some time back that shot very well with 68gr Bergers. This current acquisition (not yet shot) is a heavy barrelled single shot. I'm wondering what bullet I should try for the greatest accuracy. Should I stay heavy with 70gr or go to the light end near 62gr? Can any of you reloaders share your successes with me? Thanx~!
