? for you ballistic gurus
« on: January 12, 2016, 10:56:54 AM »
I'm looking at buying a ruger sp101 .357 with a 2 1/4 in. Barrel for a in the woods gun for predator protection. My question do I lose too much velocity compared to the 4in barrel to make it effective?
Thanks
Jim

Is the predator a stray dog, grizzly bear, or druggie?

You could lose in the neighborhood of 150 feet per second or more with a shorter barrel. Less velocity means less energy. It is true that less energy tends to make a bullet less effective (everything else being equal) but to conclude it is “not effective” would be misleading.

Nature. It's cheaper than therapy.

Thanks bob
  Where we hunt there's alot of black bear sign.I really like the size of the smaller barrel.I figured I could use .38 loads for home and hardcast .357 loads to carry in the woods

A short barreled 357 isn't much fun to shoot, but for your purposes, you'll be carrying it a lot more than you'll be shooting it. So I think it would be fine.

It will do fine, plus they fit in your back pocket nicely. Had one running around in my truck for several years.

You'll only lose a couple hundred FPS, but you WILL lose about half your muzzle energy. You can get that gun with a 3", that's what I'd do.

Buffalo Bore makes 158gr hardcast lead in 38spl+P.
It's what I carry in my 6" SW 386.
357Mag was just too violent out of that revolver.
357Mag out of anything less than 4" is pointless.

You won't find these in any store.
Your LGS will have to order them for you.

My vote would be for the 3in. version as well.  It's still pretty compact with the 3in. barrel and will also give you a bit more sight radius.

If you want to go REAL big, S&W has their 500 magnum in a 2 1/2 inch version. :tup:

Good lord, those things must be brutal to shoot, with such a short barrel. :yike:

A good part of the time I kick around the woods with a 3" S&W model 60 with adjustable sights. It's small enough to not be a bother, large enough to tame 357's (it wears Hogue grips), and enough barrel to have a decent sight picture. If I had to choose between a 2" and a 4", I'd go with a 4" that had decent sights in a heart beat. You'll get more performance from the 4" with 357 loads and be able to hit something with it. A 2" shooting 357 loads would be about the same as 4" shooting 38 spl+P ammo, performance wise.

Performance out of that with hot 158gr loads is almost exactly the same as a little compact 40 S&W with 165gr bullets, both doing right about 1100 fps according to my chrono. That was with a 2-1/4" SP101 and a Kahr CW40.

The SP101 was noticeably louder and harder to hit things with though.

I read a study many years ago, but I caution I am old and so is my memory,  :chuckle: The study compared snubs to 4 inch in 38 and 357. the loss was about 68%( not a loss of 68 , 68 remaining power so 32% loss??)
 in my memory. The 4 inch was much less than the 6 inch also. over 6 inch did not make much difference.. In a 357 I think a 4 inch is about the optimum for a holster carry gun. The model 60 S&W 357 in 5 shot and 3 inch would be cool for your use. Do not forget the 180 grain hardcast bullet for big stuff.

A shorter barreled gun that you have with you is quite a bit more effective than a longer barreled one you left at home. ;)

For all you rocket scientist and Google freaks out there. Take a Ruger SP101 .357 loaded with Corbon's jam it in your ribs and pull the trigger. Then give me a call and ask me if it works for a carry handgun in the woods.

I'm glad the majority here aren't on my left or right!
