357 Mag better than 10mm

We'll find out ….

I love that stuff. Some tests are just silly on YouTube. But this test of his put in a lot of effort. Thanks

Yes, that was more interesting than I thought. Thumb's up, too

The only reason the 10mm penetrated less is because the bullet was busy expanding and dumping energy into the gelatin.

I'd think that depending on projectiles and velocity either one would come out on top. Now, if you could ( obviously not possible) test the exact same projectile at the same velocity from the same barrel length, you'd have a fair comparison.

I'll still take the .45acp for anti personnel use and the .45 colt for bigger stuff. But I'm old set in my ways.

Is it just my speakers, or does that guy's voice seem extra deep?

He did do a good job testing the two side by side. I've never shot a 10mm, but it looks like it's very similar to the 357.

I had a 357 and didn't like the noise. The only reason I would carry one is to have a revolver in bear country. But since the 357 makes just as much noise as a 44 magnum, I would always go for the magnum. The 10MM is getting to be a popular bear sidearm nowadays and I had considered getting one because it's lighter and higher capacity than my 44 Magnum. I did lots of research and decided to continue carrying the 44 magnum for now.
Any gun comparison calls for specs in decibels.

The 357 for home protection is a no go for me. The blast and noise would blind/deafen the shooter. I prefer a 45 at standard pressures.

I sold one of my 10mm's yesterday. It was a Hi-Point and never had a jam, FTF, FTE... nothing to complain about. And it was really accurate. But since I already have 10mm in 1911, Blackhawk, G20, G29, S&W 2.0, and as of last week- Sig, I decided to keep it at 6 in the 10mm handguns; and the Hi-Point was the obvious choice since they are so bulky. I only have one 10mm carbine- a TNW. It took me a long time to warm up to 10mm, but after I did- I sold all my 45's (I still love that caliber) and my .357's. That doesn't make the 10 superior. It just means that it works well for me. I wish Ruger/Marlin or Henry would create a 10mm lever rifle to be roommates with my .44 Mag levers.

I had an email from a high profile LEO regarding penetration (paraphrased)...

"In my experience over penetration on a perpetrator never got a cop killed, under penetration has.

You picks your caliber and you takes your chances, at least this one didn't compare .38's and other mini calibers for effectiveness on bears

No bears here. Just hogs, a couple venomous snake species, and 'gators. Sneaky snakes & hogs can be a problem, 'gators not so much. Folks 'round here carry whatever suits 'em,

In my experience, the .357 Magnum has the advantage of being available in medium framed revolvers. It makes a great varmint combination as its velocity gives it some flat shooting trajectories. For awhile I carried a 2 1/2" S&W Model 19 as my daily carry gun, but have long since gone to a Ruger Blackhawk in .45 Colt for that service. From what I've seen/read o the Internet, the 10mm is gaining popularity as a revolver cartridge. But, being somewhat old fashioned, I still prefer the .44 Magnum when going afield.

There are various statistical methods that could be used to establish some reasonable comparative results, but I've yet to see anyone on YouTube set up a properly designed experiment. I consider all of these 'comparisons' on youtube to be nothing more than entertainment. Sometimes fun to watch, but not really useful.

I didn't watch the video,, but I looked at the picture of the 2 guns. I see a difference in them alone to know that there is a variable already. And as Jeepnik has pointed out,, you can get variables in projectiles & velocities etc.

And as GunnyGene has said,, you'd need to see a real comparison to get real data that is definitive.

Take a "universal" receiver,, (like used in ammo test plants,) and have (2) identical barrels of a closed breech design, with identical lengths. Both barrels brand new. Load 1000 rounds of identical ammo for each caliber,, using identical weight bullets from the same manufacturer, loaded to the same velocity. Basically,, make everything as identical as you can.
Then fire all 1000 rounds,, with testing done at 100 round intervals to see what may or may not change. I would venture that the different mass would be the one thing that would be measurable by the results. Bigger mass vs smaller mass measured by penetration results.

But that would not be "real world" results.

Many things can affect the final results of any testing. In this case,, barrel length, velocity, bullet type, bullet weight, action type, to name a few.

The debates over various calibers or firearms has gone on for centuries. And it will continue long after we are all gone. No single caliber or design will be the "perfect" one for everybody, in every situation. I teach this; "Find what gun you feel comfortable with that you can easily use. Find the best ammo for the intended purposes. then pray you never have to put it to a life altering test. Other wise enjoy what you shoot & how you shoot! "

Banana does a really good job of making his comparisons which means comparing 2 different things after all as fair as possible in identical conditions. The gel results were also as expected. The slower bullet not expanding and coming apart like the faster one penetrated deeper.

I've been shooting .41 Magnums for quite a few years. That is pretty close to 10mm if you don't know. Try comparing a .357 to .41 Mag. The only thing a 10mm has over the .41 Mag as far as I can tell is more than 6 rounds available. If I were attacked by a bear (which is not likely in South Dakota) I think I would rather have the .41 Mag 'cause if you can't stop it with one or two rounds, the other eight aren't going to do you much good. JMHO, of course.

Bears, like wolves, will sometimes do the fast circle maneuver of circling at 50 yards or so running from cover to cover anticipating the best chance to charge. In such a scenario you might be missing many of your shots and more rounds would be better.

OK then.

I am a HUGE fan of 357 mag revolvers and carry one daily, hunt with one every year and even carried one on duty HOWEVER if I am in an area where I might run up on a predator larger than a human, its 10mm. For the simple fact a semi auto is faster to reload than a revolver (for me) and generally carries more rounds before the required reload.
