This weekend I ran the Speer Gold Dot 38 Special +P 135 gr over my chronograph through my new Colt King Cobra 3" Here are the results below:
#1 - 1091
#2 - 1084
#3- 1071
#4-1109
#5-1100
Avg: 1091.0
Standard Dev: 14.6
Spread: 38
This is LE ammo in the 50 round box . Advertised muzzle velocity is 860 fps from a 2" vented barrel. When you look at the wound ballistics gel test on the vista outdoors website they show the velocity at 945 fps. Interesting ....
