my opinion is the 45 ACP round has more knock down powder then the 40 caliber
Depends on the load.
I don't believe so.......................
No
Given proper shot placement, none.
Depends on the model, all have their own virtues however the best value listed is the Springfield armory XD .40 S&W.
maybe 80 feet at 45 degrees
.17....22 Cal....32 Cal....38 Cal....9mm....40 s&w....357 m......44 special....44magnum...45 Cal....454 Cal.....500 magnum......50cal
40 grains of fffG
45 of 40 = 45*40 = 180045 of 40 = 45*40 = 180045 of 40 = 45*40 = 180045 of 40 = 45*40 = 1800
45 is more powerfull. larger bullet, more powder = s more knock down power.I own both calibers. It's obvious just by shooting each gun.
Any of the major reloading books should have what you want.
any 45 cal ammo will work in a 45 cal pistol
