Sarge Posted January 28, 2017 Share Posted January 28, 2017 So we can't duplicate threads here because they take up too much bandwidth. But we can have multiple posts resembling war and peace? So many words......... Link to comment Share on other sites More sharing options...

My testing says: trust the target. Use the chronograph to make sure you make your power factor, but don't expect it to predict accuracy. This is awesome.

superdude Posted January 28, 2017 Share Posted January 28, 2017 5 hours ago, 57K said: Actually, that would need to be looked at more closely with Standard Deviation, Velocity and Standard Deviation, Group size, while being repeated enough times to have a quantifiable population of Standard Deviation. You don;t get that from a group where the load had a charge of N320 vs. another group that had a charge of WST. You would need to look at a number of groups of varying ladder load chargeweights with ONE powder vs. the same methodolgy using the OTHER powder. If you don't believe that presrure matters; which determines the velocity achieved, then maybe further discussion is POINTLESS. BECAUSE, and you need testing equipment to prove it, but the more uniform Velocity is, it's also telling you how uniform Pressure is. We're talking about two different things. I'm addressing the method for testing the correlation between the standard deviation of velocity and group size. You're talking about comparing two different powders.

Majja Posted January 28, 2017 Share Posted January 28, 2017 many years ago when I use to shoot a 9x21 my major and minor loads were the same powder charge just different bullets. I shot a 124 for major and a 115 for minor. all over 3n37 but I do not remember the charge weight. Link to comment Share on other sites More sharing options...
