10mm vs 45 ACP which has more stopping power.

Not mine but worth posting none the less

There is no such thing as "stopping power". There are good hits and poor hits. :banghead:

10mm

Stopping Power

I've always liked this bit of wishful thinking:

I like the way you think. power Vs proficient = apples and oranges

that is just dumb

My .45 holds 8+1 rounds; my 10 holds 15+1.

So the 10 has more stopping power.

I think if you shoot stuff, then stopping power is real. You see how certain bullets and calibers penetrate and destroy matter. Shot placement has no value here. Assume the same shot placement. This isn't about what caliber you can shoot better. I think the vast majority of people shoot the .22LR better and the reasons are obvious. That is not the question.

I believe that the 10MM is superior to the 45 due sectional density, superior penetration, speed,and comparable diameter. I want a caliber than has the potential to overpenetrate becasue barriers are apart of my caliber and cartridge consideration. To that end, and in my (who gives a crud opinion) the 10MM has more stopping power than the 45 automatic.

Shot placement has no value here. Assume the same shot placement.

I'll try to make this simple. Per your post, we'll assume the same shot placement.

You shoot me in the left big toe with your 10mm at the exact same time I shoot you in the left big toe with my .45. Same shot placement, right? Think either one of us is going to give up at that point? I'm not.

While you're dragging your 10mm back down out of recoil I shoot you twice in the chest with the .45, then empty the rest of the magazine into you on your way down before I reload. We never get to see the "stopping power" of your follow-up shots since you never make them because you're dead before you can get them off.

Which caliber had more "stopping power"?

Real Life Experience

My wife repelled a front-door-crashing daylight intruder with her Glock 23 without firing a shot. She raked the slide and was prepared to defend herself. However, the intruder, who was 20' inside our house, heard the slide being raked and turned tail and ran. The final investigation report reached this conclusion; not me or my wife. But we agree with it.

Awesome stopping power there. Never knew a small sound could have stopping power but sure did in this case.

After all "stopping power" does mean to cause the threat to go away, i.e. "stop" the unfolding event. The threat went away so the sound of a Glock slide being raked has "stopping power".

All depends on your definition of "stopping power" I guess. But that's another contention for another time.

Food for Thought

My carry load: Win Ranger .45ACP @ 400 ft-lbs energy

My hand-cannon load: 10mm handload @ 800 ft-lbs energy

I carry the .45.

The 10mm is a high velocity round that fires a 40 cal bullet at very high speeds. while the 45 fires a big 45 caliber bullet at a slow speed but still hits very hard. Both seem to be at the opposite ends of what makes up good stopping power, small and fast vs big and slow. Which one do you think has better stopping power.

Well, in practical terms both will get the job done. As others have exhaustively pointed out, shot placement is more critical that caliber. I would agree with that as far as it goes.

The 10mm is clearly faster and more powerful, but I sincerely doubt that anyone could describe a shot that would be fatal with a 10mm that would not be fatal with a .45.

I prefer a 10mm because it IS more powerful, and because it allows for greater magazine capacity (but a .45 would be just fine too).

With all that said, I still like my P85MKII in 9mm when loaded with +P hollowpoints. I have full confidence in that gun and that caliber.

My 10mm holds 15+1; my .22 WMR holds 30+1.

So the .22 Mag has more stopping power.

--- Sorry... couldn't "stop" myself.

BTW, I don't have a 10mm nor a .22 WMR.

The one you make more head shots with.

45Auto, while I see your point as to ability to shoot better with particular caliber, that was not the question nor does it have anything to do with my response. I don't disagree that follow up shots, and placement are important...... we agree there.

I'm only looking at the capabilities of one cartridge verses an other - yep its the caliber war issue. My night stand gun is either my ccw40 or my trusted 1911 45. But I still stand behind my opinion that the 10MM is superior in stopping power to the 45 automatic. Other than shot placement and how well one can shoot a particular gun, is there any other argument to my statement? I'll listen.

I think that depends on whether you believe that any handgun rounds are capable of shock/TWC/BPW-type incapacitation in even some instances. If you think that never happens, I think you're right. If you think it ever happens, you might conclude that a 10mm is fast enough to get that phenomenon some of the time but the .45 isn't. (I express no opinion on whether the phenomenon occurrs, or occurrs frequently/reliably enough to be a factor in caliber selection.)

Here is my standard answer for "stopping power" -

Ok so if on your scale of 1-10, and that is a 5, I'm pretty sure that leaves all handgun calibers around .001 on your scale

This is why I carry a 357 sig.

Both the 10mm and 45 kool aids taste like garbage to me

The 10mm Glock G20 is the exact same thickness and the .45ACP G21, thus they both have equal stopping power when used to chock a wheel.

But the Glock 20 holds 15 cartridges vs only 13 for the Glock 21 in .45. Assuming that there isn't much slope, we can chock one car with the gun, one with the magazine, and 15 additional cars with one round of 10mm each.

The Glock 21 can only chock 13 additional cars with the rounds in it's magazine. So the 20 has more "stopping power", since it will chock 17 cars while the 21 will only chock 15.

However, if the slope is slightly steeper, the additional diameter of the .45 cartridge will keep the cars chocked while they will roll over the smaller 10mm cartridge. In that case the 21 would have more "stopping power".

Whichever hits the target and vitals.

I think that this was predestined to "go off the rails" from the start. Looks like it is right on time.

Ill take a 45 ACP bec thats the one i have and familiar with .

Six in one...
