I traded for a N.E.F. Model R73 32 Mag H&R Revolver about 10 or so years ago. It came with ammo, but some how got missed placed over the years. I just brought home a box of 32 AUTO 71 GR. FMJ...

My question is: "Will I lose a finger if I pull the trigger? :eek: ". Please be easy on me, I know it may be a stupid question... Hadn't needed a gun in my hand for sometime. Moved back to home town, and notice it had turned into CRANK USA, OK. Just need something that makes noise, not worried about take down power.

Just need to know, or where to go and find out if this pistol will fire the round... The Cylinder matches right up the the back of barrel.

Hope I posted in right section. Forgive me if I posted in wrong section. Thanks in advance for any info.
 
I'll second Sir William's advice. DON'T!

It might actually be possible to fire it, but you're risking a serious injury. Stick with .32 S&W Long or .32 H&R Magnum. If you just want noise, use .32 S&W blanks.
 
I figured it to be that way. Googled for about an hour couldn't find any info on subject. Thanks a lot guys, I'll take your advice to heart...

Thanks again.
 
Actually 32 mag chambered guns will shoot 4 cartridges. The bullets & cases are all the same diameter, the only difference is the length and the pressure level they are loaded to. I have shot 4 different brands of 32 acp in my ruger with no problem and so-so accuracy.

Here is the text from an earlier post.

Next, I have read on this site about people shooting 32 acp’s and 32 S&W in 32 mag chambers. This made me wonder about bullet jump to the cylinder throat. How far does the bullet have to jump from the end of the case to the cylinder throat?

I wondered if the bullet was supported or guided for this jump. Does it float along like a log in a stream? The other thing that happens is there seems to be nothing to seal the powder gasses behind the bullet while it is making its millisecond free float in the chamber. I looked up the various cases and their lengths that can be chambered in the 32 mag. I subtracted the case length from the 32 mag case to get the possible bullet jump.

The 32 S&W case length is .605 difference =.470
The 32 acp case length is .680 difference =.395
The 32 long case length is .916 difference =.159
The 32 mag case length is 1.075 difference =0
I just measured a 77 grain case bullet and the bearing surface is .27 in.
90 gr cast lead and the bearing surface is .20
Hornady 85 gr XTP and the bearing surface is .290

To me this looks like the bullets from short cases will have .125 to .200 to float in the chamber with gas blowing past and unsupported.

We know people have been shooting 38’s in 357 chambers for a long time with great success. The difference in case length there is .125 in. similar to a 32 long in the 32 mag.chamber.


The point of impact for all of the above ammo was within 3 inches of each other at 50 ft.

Big Grin

I've shot .32acp in my S&W 432PD. No pressure problems, no obturation problems (meaning no gas blew back up the cartridge), primer looked great, no fouling, only problem I had was that it grouped 6" or so at 7 yards with what I think were 71gr FMJs.
