358Win:
Yesterday tried your fire-forming tip. Worked great! Fired 40 rds of factory Winchester 150 gr loads. Like you said, perfectly formed 358s. Of course, it did leave lots of unburned powder behind, and a guggy muzzle. But it all cleaned up easy. Tried some 200 Hornady/Win 748 loads: three 3 shot groups average 2 inches @ 100yds. Have you had any experience with H335 in this caliber? Since I'm new to both this caliber and rifle appreciate any tips.
