[QUOTE="P7M13, post: 1911327, member: 94154"] I mean no offense. Problem is, CUP uses known, calibrated alloys, methodology and equipment. IMO, chamber differences, brass alloy differences and measurement methodology make enough variables that, for someone not familiar or inexperienced, is an invitation to potential disaster. As to alloys, look at the differences in brass behavior between Hornady, Lapua and PPU brass. While I havent measured case expansion, I have recent tests where the same load in the same rifle ruptured R-P and PPU brass but not Lapua or Norma brass. Years ago, I stopped obsessing about velocity and with that, stopped pushing the limits, and no more pressure signs. Ultimately it's about precision and accuracy. I imagine your measurements are valid for your methods and rifle. Do your thing. I know men who can lick their finger and tell you wind speed, who can look at different flags or mirages and accurately gauge how it will affect their shot. I am in awe of them. My personal favorites are the golfers I knew as a caddie who could read the green and had the skill to place their shot so it rolled close to the cup. When they could do it 10 out of 18 times, it wasn't luck. [/QUOTE]
