.32 semiauto = .32 revolver ammo?

[psyprofessor]

hey guys...maybe you can help me on this one...

1. S & W makes a revolver chambered for .32 (I believe the ammo is .32 HR) Not sure what "HR" stands for???? Is this ammo interchangeable with .32 semiauto round? (such as P32 Kel Tec?)

2. If not, which is better for stopping power?

The "HR" stands for Harrington & Richardson . The .32 H&R is an improved .32 round that was developed from the old .32 Long in 1982. The .32 H&R has about the same power as an .38 special. To the best of my knowledge there is no way to use .32 ACP (The semi-auto round you mention) rounds in a firearm chambered for .32 H&R or .32 Long. The .32 H&R cartridge defiantly is better than the .32ACP. My recommendation for you is if you are looking for a .32 revolver get one of the new Ruger SP101's chambered in .327 Federal Magnum. The .327 has about the same ballistics as the .357 but in a smaller round. You can also fire .32 H&R, .32 Long and (Correct me if I'm wrong someone) the old .32 S&W in the newer guns chambered for .327 mag.

32 acp is semi-rimmed. roll it on a table top and it scribes a arc. it fits and fires in all my 32 S&W short (careful as a factory 32acp is hotter than a factory 32 short) and long revolvers and 32 H&R's. not much power or recoil and very accurate also. it will work in the newer 327 also. all else is correct briancraig.

Correct; the four rounds, .327, .32 Mag., .32 S&W Long and .32 S&W have the same case diameter and rim size, so a revolver chambered for one will accept the ones to the right. In addition, the .32 ACP is semi-rimmed and can be fired in revolvers chambered for the above, but that is not recommended for older revolvers chambered for .32 S&W or .32 S&W Long, since the .32 ACP is a higher pressure cartridge.

Learn something new everyday My dad bought a H&R revolver in .32 H&R a while back. Local gun dealer told him .32 ACP would'nt work in it. I'll have to tell my dad that the fellow was wrong about that.

because the rim on the 32 acp is a bit smaller then the regular 32 mag/long/short, it may have extraction issues.

in thought, isnt a 32 long going to give better penetation then a 32acp?

Well, he wasn't completely wrong. It isn't chambered for .32 ACP and they are not interchangeable. It MIGHT fire the acp rounds, but performance will be better with the .32 revolver rounds. If .32 auto is all you have, go ahead and shoot it (it worked about 50% of the time in the H&R I tried it in; light primer hits on the acp rounds), but don't purchase .32 acp to shoot in your .32 revolver.

because the rim on the 32 acp is a bit smaller then the regular 32 mag/long/short, it may have extraction issues.

In my SP-101, the ejector star sometimes slips past the .32 ACP rim. If one plans to shoot .32 ACP in a wheelgun, carry a pocket screwdriver to poke out any cases that may not extract.

Otherwise, the .32 ACP in a heavy pistol like the SP-101 has virtually no recoil and is a whole lot cheaper to shoot than .32 H&R mag.

Another factor to consider is this.

The .32 revolver family uses a .312" bore diameter & .312" jacketed or .313" lead bullets.

The .32 ACP uses true .30 caliber, or .309" bullets.

I would expect gas blowby, and less then steller accuracy.

The .327 has about the same ballistics as the .357 but in a smaller round.

The .327 has about the same ballistics as the old .32-20. The latter will drive a 110 grain bullet to around 1500 fps (from a 7 1/2" barrel.) By contrast, the .357 Mag will drive a 125 grain bullet to about 1800 fps from a 7" barrel.

It's pretty hard to find revolvers chambered in unpopular cartridges though. It's hard even finding anything in .38 special anymore in my town (other than the airweight craze going on now, and most are still .357) .


And looking at the foot/poundage numbers, it's in favor of the .32 h&r, if you don't mind the bigger gun to tote around.
