[QUOTE="Bob Wright, post: 2170236, member: 104363"] The biggest problem is variables in brass and prep. Therefore there is no clear cut way to do a calculation with 2 or more variables. Just prep your brass the same way, and then experiment with one thing at a time. The goal is to get a minimum sample size, like 10, and measure velocity variation. Try something else in a logical manner to see if variation gets smaller. I cannot see putting all this thru a math analysis and getting a meaningfull result. It simply needs careful consistent brass prep and trying incremental documented steps to improve. I have 40 years in aero engineering. There is little that calculations can do to solve the myriad variations except bench experiments, consistent prep and chronograph results. It's more old school basic approaches as much as I hate to admit it. Once you master one chambering, you have a good foundation and start point for all others. [/QUOTE]
