Depends on the load.
my opinion is the 45 ACP round has more knock down powder then the 40 caliber
I don't believe so.......................
No
a cheetah can run faster than that, and an ostrich can run about 45 MPH
Given proper shot placement, none.
85-40 = 45 and 45+45 = 90
maybe 80 feet at 45 degrees

yes it can lions can run 35 to 40 mph but ostrich run 40 to 45 mph.
Yes, a 45 caliber bullet is bigger than a 40 caliber bullet. A .45 is0.45 inches wide in diameter and a .40 is 0.4 inches in diameter.
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.
