Which is Better? - 10mm or 357 Magnum

Of the same weight and velocity two different diameter bullets…the smaller diameter bullet penetrates further.

Of course there are other factors like how the bullet is constructed which could give more or less expansion, if any. A bullet that bumps up quickly will slow the bullet down faster, imparting more knockdown energy.

If a bullet passes threw a target without expansion it leaves a pencil hole clear through. If it’s through the vitals you’re dead. If a bullet expands rapidly in the vitals you’ve dead quicker but still dead. If a bullet expands upon impact (varment loads) on a large target like a human. It imparts all its energy right that away and knocks you down. But if it doesn’t hit the vitals you probably will survive it.

I could go on.

Norway issues the 10mm to soldiers for protection from polar bears.
The 10mm was taken away from the FBI because too many of its members couldn’t handle it.
I love my 10.

[Lurker]

“I could go on.”

Indeed. It’s why the subject is so fascinating to me.

He’ll first they lowered the power of the 10 to 40S&W. Then the little girls they are hiring for agents found this too rough. Now they’re down to 9MM. .

[Vinnie]

I would never recommend anything but a revolver for anyone who does not shoot often and become very experienced.

Amen.
Also your bedside piece.
Awoken in the middle of the night. Is there a round in the chamber? safety off? magazine in and locked?
And just the stress of the situation. You need the foolproof piece with the long stiff trigger pull. No 'it went off accidentally' stuff.

.357 with .38+P hollowpoints. (save your ears)

[Vaquero]

Just went to a local “toy” store to buy powder. No powder. I usually buy it on line but it’s not worth paying hazmat fees for just 1 lb I want to try. If I like the results I’ll buy 8 lbs. now I’ll work my way to another store. But not today.

[Lurker]

I buy bulk, too. Got some milsurp Winchester stuff and stocked up on Bullseye, Unique, Varget, and some CFE. Not enough to require a purpose built magazine, tho.

Buy cheap, stack deep. Right?

LOL.

I'd recommend the .357, for the simple reason that if you don't reload, you can shoot A LOT of practice ammo using .38spl wadcutter commercial reloads, and with the lower recoil, someone who doesn't practice that much will be less prone to develop a flinch from shooting full combat loads all the time.

Revolvers are also simpler to shoot, and in some cases, safer - You don't have to worry about a round being chambered or not. And dealing with a failure to fire is simpler, as well as not having to deal with a jam.

But you really can't go wrong with either.

Neither could some of the guns! A buddy's Delta Elite wound up with a cracked frame (stainless,) and Colt said it was the "factory ammo," and told him to buy another.

When I shot competitively, I'd buy 10,000 primers at a time, and would very carefully label the WW-296 and WW-231 canisters and powder measures. Very bad things happen when you get the 2 mixed up...

I actually became very fond of Scott Powders, and had great luck shooting pins using "Royal Scott" in both my .45auto and .44mag pin loads.

I reload but carry Underwood 220 on the trail. About 4 feet of gel penetration.

Learned some good lessons via Underwood.

I bought a glock 20 and wanting to get the most out of it, I ordered Underwood's full power loads (as opposed to the light loaded 10mm, giving .40S&W velocities everyone else is marketing).

. Now don't get me wrong, i love glocks and i respect the 10mm, but for me, the two didn't go well together. There's just not enough mass in a glock to shoot 10mm comfortably. I'm sure a 1911 frame would be a hoot.

Nevertheless, after six rounds, i took it up front and traded it for a 9mm Sig ;-)

[dangerdoc]

Funny, I had the opposite experience, I’ve shot Gov Models for 40 years, I used to wear shooting gloves because they were uncomfortable to shoot. I got the Glock 20 and full power ammo and expected to be beat up. I was surprised that it felt more comfortable than shooting 45 Auto in a steel full sized Colt pistol.

[YogicCowboy]

Good point: public safety.

[YogicCowboy]

Yes, but that does not really dispute the earlier point: They are not typically in a crowded apartment building shooting through a drywall.

The early Colt Delta Elites had the cracking frame problem, the newer ones don’t.

[Mr Rogers]

“Pow,Pow,Pow,Pow,Pow,Pow,Pow,Pow,Pow,Pow,Pow,Pow,Pow,Pow,Pow,Pow,Pow.”

A guy who had to hunt man-eating lions (George Adamson, made famous in the book Born Free) was asked about hunting them with a double rifle. “How do you do it?”, he was asked. “Isn’t it dangerous with just two shots?”

“Wait until 10 yards. Don’t miss.”

[Big Red Badger]

.38 +P JHP thru a 4” stainless RUGER,
That’s a joy to Shoot!

[MarkL]

The early Colt Delta Elites had the cracking frame problem, the newer ones don’t.

I had been under the impression that the problem was more due to the high powered 10mm loads initially used. Maybe I'm wrong, but given the original 10mm loads, I seem to recall that the original Bren-10s also had a very short service life. I thought that the ammo manufacturers "toned down" the standard 10mm load, but maybe I'm wrong.

You should see the magazine!

[Celtic Conservative]

Either will do the job if you do yours q in terms of shot placement. When I see these X vs. Y comparisons i always have to ask- can you hit anything with either one?
