Hello. A while back I noticed .45 GAP making its debut into the shooting world. Having chronographed bullets in flight from various handguns in different calibers and action types, I noticed very similar characteristics to the degree that there is more than a little overlapping in performance.
For example:
Browning 9mm Hi Power:
Corbon 125-gr. JHP +P
Average Velocity: 1312 ft/sec
S&W Model 28 .357 Magnum w/6" bbl:
Federal 125-gr. JHP
Average Velocity: 1358 ft/sec
The .357 beats the 9mm, but also has a bit longer barrel.
From a 6" bbl FN Hi Power Competition, I got 1348 ft/sec from the Triton 125-gr. JHP +P, which is darned near the same velocity.
S&W Model 58 .41 Magnum w/4" bbl:
Corbon 170-gr. JHP
AVerage Velocity: 1333 ft/sec
Colt 10mm Delta Elite w/5" bbl:
Winchester 175-gr. STHP
Average Velocity: 1288 ft/sec
These two are pretty near equivalent on the receiving end, I'd think.
Comparisons can go on and on, but I sort of think we have
enough different cartridges to choose from. (Of course, with that thinking nothing new and maybe better would come along, but at the same time it appears to me that we're just duplicating terminal ballistics from different "packages."
I can understand the desirability of perhaps ballistically equivalent rounds that are physically smaller for use in a wider variety of handguns, but other than that, it appears to me that the bases are pretty well covered.
What do you think?
Best.
