Figuring Energy of a round
A lot of times when I quote a Velocity from one of my tests I'll also quote the Energy. Some of you might wonder how I come up with these numbers( No Mike, there's no room for them in my posterior). Chuck and I use the Factory standard formula for figuring Energy in a round.
Velocity times velocity
450400
Times bullet-weight =FPE
For example; a 158 grain bullet at 1250 fps.
1250 x 1250 divided by 450400 times 158 equals 548FPE
