[QUOTE="bigngreen, post: 1537611, member: 13632"] Well, if by your reasoning only pressure = velocity then regardless of powder 60k of pressure will produce x velocity across the board and we all know at a basic level that's not how it works since pressure is not the only driving force behind velocity. Apply that to an apples to apples case volume and you can manipulate other contributing factors and see a velocity gain, I can load the same exact load in the SAUM and SS and despite volume being exactly the same the velocities are not close enough to be inside a barrel to barrel difference. I've done two nearly identical builds in a 7saum and 7 SS and using the same lot of brass and powders performance is obviously different. There is abundant proof all the way from the most basic level of relaoding if you don't make your mind up based on a less complete understanding of the subject. You asked if anyone had ran pressure traces and I have on some cartridges including the Sherman but you don't like the answers cause they aren't fitting your understanding. Others have pressure traces in this thread and have seen things that make a difference that you wouldn't think would and other things making a big difference that others disregard. [/QUOTE]
