[QUOTE="Mikecr, post: 1383124, member: 1521"] It's because your reference in this case is expected velocity from a manual, which is not calibrated to your components, including bore dimensions, bullets, seating, and powder lot differences. So if you think 3kfps is max based on a manual, this may be wrong, and then a change leading to 3.2kfps, may still mean little about max or safe pressure. Differences could be the result of different powder burning differently in a different bore with different bullets (lots to lots). MV is input, and all input could be useful. Just be careful that all your inputs are not tainted by (w/resp to) single [U]assumptions[/U]. [/QUOTE]
