[QUOTE="Rhovee, post: 2051032, member: 101820"] I had a 30/28 Nosler that shot 86 grains H1000 for 3090 in a 26” barrel. Friend picked up a 300 Norma. Which has same capacity. 103 grains. Guess what. He shoots 86 grains H1000 with 215 at 3040. So even though case designs are completely different. They both shoot very similar powder charges. Volume is volume in my book. Sometimes you AI a cartridge to run next node up that would be to much pressure in original cartridge design. 40 degree masks pressure. Polish the chamber, Add extra on *** end of reamers, and you can run some high pressure. I like some/most of Sherman’s designs and ideas. But it comes at a cost (barrel life) when running big numbers on smaller cases. [/QUOTE]
