I agree on the velocity's "Importance" given for the FPE formula,
Imo for thick skinned game, velocity is the least important factor. Bullet weight, calibre and construction far more important.
Tried some examples ....
.308 X 150grs X 3500fps = 161,700
.510 X 570grs X 2000fps = 581,400
OK maybe the velocity in the formula isn't as dramatically skewed as I first thought. After trying some examples.
I stand by my statement that the Velocity is VITALLY important for the FPE formula as I said.
That formula was used to show an advantage for high velocity ctgs. compared to lower velocity rounds of the same diameter - ie: WTBY's. We ALL know that bullet weight, construction and diameter are just as, if not more important than velocity.
The FPE formula is not a good one for 'showing' killing power. We also all (I would hope) know that to be true.
A .22-250 with a 40gr. HP bullet produces the same FPE as a .45/70 BP round with 500gr. bullet. I know which one I would rather have for moose and bear shooting. There are so many such comparisons one could make.
