I've been loading for my Sako TRG-S M995 in 7mm STW, 26" 9.5 twist barrel. I've tried 120 and 150 gr. Barnes, 150 gr. sciroccos, and 168 gr. smks; in front of h1000, 7828, 4831, and rl22. I have yet to get under 1" vertical variation. I have tried everything in my sleeves. So before I spend a couple grand to re barrel is there any ideas on what I may be doing wrong? I've loaded coal from recommended minimum to max that fits in the mag but in my experience Barnes liked to be jumped so I can't imagine that to be the problem. And no I have not scoped the barrel. Has around 500 rounds. Any info even criticism is more than welcome.
