Fastest potential incapacitation 45 or 10mm ?
Here are two loads with nearly the same recoil:
Hornady 155 XTP 10mm or Winchester Ranger T 230 45.
Let's assume shooting them from a similar platform like a Glock 29 SF or 30 SF, keeping this simple.
Felt recoil as calculated by power factor (PF) is nearly the same, although that's not relevant to incapacitation.
Hornady 155 XTP @ 1,278 fps / 562# KE / PF 198 (.88 momentum)
Ranger T 230 @ 874 fps / 390# KE / PF 201 (.89 momentum)
Yes, both would work just great for SD, but...
Which load has the greatest incapacitation potential against a violent, armed, drugged...ect... human attacker, assuming equal shot placement?
Please avoid other considerations and just stick to which would (could) have the quickest potential incapacitation and why.
Ammo selection, availability, practice, and I wouldn't want to get shot with either are not points of contention. :duh:
Premium .45 HP bullet with 390# KE or 40 HP bullet with 560# KE, hitting the same spot; which is more likely to stop immediately stop the attack?
Yes, it is diameter vs KE, but this seems like a close contest. :undecided:
