.45ACP barrel length?

[Alan in GA]

here is the 250 Speer SWC swaged FACTORY bullet. Also one I recovered from an 8 pt buck after penetrating about 24" [entered rear of abdomen, travelled thru and out of chest,,entered and stopped by left front leg which was amazing to be able to recover the bullet!].
The middle bullet is a 325 grain meant for .45 Colt also. The last is a .358" meant for the .358 Winchester rifle I once had.
