Impossible to answer without knowing which 45 you are referring to. 45 ACP, 45 Colt, 45 Magnum, etc..
The maximum effective range of a .45 caliber bullet is approximately 120 meters.
25m
@ 50m
The effective range of a typical shotgun is about 45 meters
~400 meters effective range (Lethal and predictive) ~900 meters Firing range ( CAN be lethal from 400 to 900 m) ~2000 meters maximum range (maximum range the bullet can travel away - fired in a 45 degree angle)
The maximum effective range for a typical 9mm Parabellum handgun is about 50 meters. The bullet can be driven to a maximum range of over 1000 meters- when fired at a 45 degree angle. This will have no accuracy, and can only guarantee the bullet will hit the earth- somewhere.
Can't be answered without knowing which 45 you are referring to. 45 ACP, 45 GAP, 45 Long Colt, 45/70 rifle round, 45 blackpowder, etc. and from what type of weapon it is being fired
It depends on what you mean by "terminal". Are you referring to maximum effective range or maximum range?
The range of projectile is maximum when the angle of projection is 45 Degrees.
1/4 mile plus- the EFFECTIVE range is about 50 yards
At 45° angle.
The answer varies, depending on WHICH .45 caliber bullet, and which weapon fires it. In the case of the 1911A1 pistol, in .45 ACP, firing a standard 230 gr. round nosed bullet, when elevated to 33 degrees, the bullet will travel 2096 ft. Not accurately, but that is it's maximum RANGE.
