Energy (Snub nose revolver vs. compact auto)

[BlindJustice]

I've looked at the balllistics by the Inch web site comparing varaious loads/cartrides by barrel length. and somebody points out besides just the
by the inch T/C congtender cut down table below that is another table with
velocities for the same loads from real guns of vaious barrel length.

For example: the 5" T/C Contedner is pretty close to the Para 1911 5" and so on....

I did this & determined I don't want a shorter than Commander length
.45 ACP platform. I'd like a CCO format for carry instead
of the full size I carry

I also have a J-frame S&W .357 Mag

It's a Model 60 3" Bbl. with the ramp front/Adjustable rear
all stainless steel gives it a 24 oz empty weight.

My usual HD/SD load is .38 SPecial +P Double Tap GDHP rated at 1125 fps out of a 4" Bbl. controllable recovery - it would be nice though if chosen
for a walkabout/hike to put some full house .357 mag in it but I'd want to
get some of the herretts Jordan Trooper stocks for it for better control.

Finally had the time to check out the 10mm. This is a very impressive cartridge. I had always just thought of it as a small .45 acp. The velocity and energy is very impressive in some of the Buffalo bore and Corbon loads. I can't wait to shoot one and compare it to a .357 mag.

I can't wait to compare the Glock 29 and Ruger LCR .357.

\\when you take a round that is tailored for longer barrels and shoot it out of a snubby you lose a lot of power. the powder burns slower to accelerate it down the full length of the barrel, you can really see this once you shoot a .357 out of a rifle and it's going 1800+ fps. even out of a snubby though a regular .357 round will have more energy than a +p 9mm. the fastest i have seen a +p 9mm come out of a compact (actually the only time i've ever seen a 9mm chrono'd ) it did about 900 fps out of a 3 inch barrel. this is about the same that my 2 inch snubby does with regular ammo but it shoots heavier 125 and 158 grain bullets that fast, the 9mm was only 110 grain. you can find ammo tuned for short barrels, buffalo bore and double tap have ammo that comes out of a short barrel at blazing fast speed, i have seen around 1200 fps with bb on my 2 inch and around 1350 with double tap on my 3 inch. the good thing about the bb load though is it's low recoil, shoot it after shooting the double tap and you will come to appreciate it.
