True or False: .45acp or 10mm For HD

[TarDevil]

I've shot both outdoors, but never shot the 10mm indoors.
I was shopping for a S&W .45acp for my night stand and my LGS salesman whipped out the S&W .10mm. I voiced my concern over the 10mm blast indoors and he said, "No different than .45acp."

I'm voting "False!"

I have shot both at an indoor range both had similar length barrels, the 10mm was alot louder. That was with plugs and musffs.

I have to agree with jak67429. The 10mm on an indoor range is quite a bit louder.

I will also add that the 45acp round is typically subsonic at >900fps while the 10mm rounds is supersonic. That being said, the 10mm round should be louder as it breaks the speed of sound (crack).

Which one did you end up going with ?

Maybe the salesman is about 95% deaf from shooting without proper hearing protection.
Seriously, I also vote "false." I don't have the data sitting in front of me right now, but I'm pretty sure the 10mm is loaded to higher pressures than the 45 ACP. That would make the 10mm "louder" than the 45 ACP.
Not that I'd want to fire either one of them without proper hearing protection (especially not indoors) unless I had to. I've lost more than enough of my hearing already by being stupid - like shooting without proper hearing protection, when I didn't have to.

I have never used a decibel meter to verify but the report from a 10mm is considerably louder.
I went with false.

. . . and he said, "No different than .45acp."

And you didn't break in out laughing?

 

[357 Terms]

SAMMI pressure for the 10mm is set at 37,500psi
The 45 ACP is 21,000 psi

If you shoot it without hearing protection,your ears get used to it. ;-)

 

[sparkyv]

False.

 

[WrongHanded]

10mm is louder. Supersonic makes a difference. Having said that.....

If a gun being a little louder is really a concern to you in a life and death situation, you might want to reassess your priorities.

 

[gyp_c2]

If the load values were close, I suppose it's possible muzzle blast would follow.
The loads I've shot have NOT been comparable.

 

[TarDevil]

Which one did you end up going with ?

Still can't find the S&W .45.

 

[TarDevil]

And you didn't break in out laughing?

No, but I think the owner looked at him with a smirk!

If I thought the .45 was giving up a significant advantage in defensive properties, that concern would be summarily dismissed.

It seems to me that the difference between the two would be largely based on the particular firearms, and the ammunition selected.

It's always the whole package. It's why most of us own numerous firearms.

Louder and the recoil pulse is..different.

I can shoot a 40, 45, 357, 41, 44, 460 but can I hit the inside of a barn while Im in the barn with a 10mm.....Hell no. Plus its loud

 

[SDGlock23]

It really depends, it's not so much the caliber all the time as the powder used in it. I've heard .45's that weren't excessively loud and yet I've heard .45's that sounded much louder and boomier, it all has to do with the powder used. Sure a 10mm could be louder, but a particular .45 could be louder than a particular 10mm, it all depends.

 

[FL-NC]

I'm going to say either of those are going to be too darn loud and mess up your hearing without protection indoors or outdoors. Then there is the question of how many rounds end up being fired.

True: You need a new LGS salesman.

Either that salesman wanted to move an idle gun or has no experience firing either cartridge.

 

[Madcap_Magician]

I still have this strong desire, which I can neither explain nor defend, to get a 10mm.

If you shoot it without hearing protection,your ears get used to it.

I mean... that's one way to put it.

 

[bangswitch]

If you reload, it's relatively easy to get 10mm Auto loads that are very similar to .45 Auto loads. Use a 200 grain JHP loaded to around 800-850 fps. You still have the ability to ramp those up significantly if you want or need to. I've got 1911's in both .45 and 10mm, I shoot the 10mm more than twice as much.

But yeah, indoors or out, standard 10mm is a lot louder than .45. If the noise bothers you indoors, wear plugs inside a set of electronic muffs.

 

[Choctaw]

I regularly hunt with a 10mm and practice with it even more. It is loud but so is any centerfire handgun fired without hearing protection. Anything that makes your ears ring takes away a measure of your hearing that you will never get back. Ask me how I know.

 

[Crazy Horse]

Still can't find the S&W .45.

I have a LE turn in with the 4.25 barrel and a shield 45. Both are awesome. Naturally the one with the longer barrel is more accurate as you go out, but the shield 45 is excellent for CC.
