Does anyone else calculate the Taylor Knock Out Factor when looking at loads and different cartridges.
https://en.wikipedia.org/wiki/Taylor_knock-out_factor
A simple calculation helps put a number on what I call hammer effect.
mass x velocity x diameter = sum ÷ 7000
Some Underwood hardcast loads.
9mm +p 147 grain @ 1100fps = 8.1
45acp +p 255 grain @ 925 = 15.2
38+p 158 grain @ 1250 = 10.1
10mm 220 grain @ 1200 = 15.1
It may be fun to look at your favorite loads or start an argument, but it should be a fun discussion
