7mm/08 Remington VSSF barreled by Pacnor with a extra heavy Sendero contour barrel 26" 1/10 twist, skim bedded into the Remington HS stock. Lapua 243 brass fire-formed to 7mm/08 chamber. Hornady 162 A-Max and Berger 168 Match bullets. H4350 and H4831 powder, 210GM primers.
I've tried 8 different combos and I'm getting vertical stringing with everything. Groups are 1/2 to 1 inch tall by less than 1/4 wide.
Any Ideas? I'm thinking primers?
