FPE is irrelevant to the killing power of an air gun, except that enough FPE is needed to give the pellet or bullet the energy to shoot into and thru the vitals. Beyond penetration, FPE does nothing. Airguns kill by the size of the holes they make. They kill basically like arrows. A whitetail deer will die fast from a .30 hole from the lungs, much faster than what a .17 firearm will offer. The energy of a .17 powderburner is also inconsequential to killing large game, because it still doesn’t have enough energy to cause hydrostatic shock. What you’re left with is a .17 hole in the lungs vs a .30 hole thru the lungs. The .17 hole will clot and let the lungs re-inflate, the .30 hole will not.
That a .30 airgun has the energy to provide a double-lung shot on a whitetail with full penetration is beyond question. Even the mathematics bear it out. A 50 grain .30 JSB at 900fps will provide about 15 inches of penetration in ballistics gel on paper, and my experience has been that real world testing always outperforms the formula. Its the same energy an arrow has.
The only argument really is whether a .30 hole shot thru the lungs is big enough to stop the lungs from reinflating upon depressurization. We say that it is.
