One more point to bring up. I load for a friends 30 06 Sig Rifle, that shoots Norma 165 grn deer loads so perfectly, its remarkable. Low in the bullseye at 50 yards, HI in the Bullseye at 100 yards, and approx. .060 to .065 shorter than the 3.340 max COAL. I do not know what 165 grn bullet Norma uses is that load, but if I load 165 Grn. Horn SST at 3.330, the bolt will not close. The Bolt will not close even at 3.320 with that particular Hornady Bullet. It needs 3.290 for the bolt to close with some force, with that Horn 165 Grn SST . I make his loads 3.280. Feeds and functions easily . Every Rifle is its own story!!
