32 cal swap ?

Can I run 32 auto rounds through a 32 h&r magnum gun??

Dan-O · December 3, 2017, 10:31 PM

Technically yes. Although my .327 LCR only ignites .32 acp about 60% of the time.

Thanks for the link.

Answer is "reliably no". Rim is smaller on the ACP. That's what I understood.

The gun is question is a revolver. If anyone asks.

TruthTellers · December 3, 2017, 11:02 PM

It's safe to fire in a .32 H&R Magnum chambered firearm, but depending on the gun, the firing pin may not be able to reach far enough and hit the primer hard enough.

Ejection may be a problem with DA revolvers as the ejector may slip past the tiny rim of the .32 ACP. In the event this happens, poke them out with a wooden dowel or something.

If you're asking about this because you don't want to "pay high prices for .32 Magnum ammo" the .32 S&W Long wadcutter ammo made by Fiocchi, S&B, and other non-American manufacturers can be found for the same price online as the .32 ACP can. .32 Long is accurate and more powerful than .32 ACP.

.32 S&W long is not more powerful than .32 acp.
Wrong again!

Green Lantern · December 3, 2017, 11:52 PM

Yes, the 32 mag is $1 per shot.

100 grain bullet going 750 fps is more powerful than a 60 grain bullet going 900-1000 in my book.

Actually, 900 fps with a 100 grain bullet if you buy the right ammo:

Yes, it is and it's like that for all .32 Mag ammo.

What revolver is this? S&W? Ruger? H&R? If this is an H&R made .32 H&R Mag revolver, I might actually say don't shoot .32 ACP in it. Those were not well made guns, I don't know if they're capable of shooting sustained amounts of the higher pressure .32 ACP.

If this is a Smith or a Ruger, you're all clear.

If you're mostly looking for cheap range ammo, .32 ACP might work in your gun, you have to try it. If you have issues, buy the .32 S&W Long. Here's a link to the cheapest ammo I could find:

I'd also go for .32 S&W Long. I got a good deal and stocked up on 98-grain SJHP from Magtech a few years ago. No, they are not as powerful as .32acp. No, I wouldn't expect dramatic expansion. They just work and they work well for my limited needs.

The original question has largely been answered but if you want my two cents, I'd only ever intentionally feel .32 acp to my .32-caliber revolvers if I was totally out of other ammo and was in some kind of rare crisis that left me no other options.

JERRYS. · December 4, 2017, 08:33 AM

using standard math I don't find the .32 Long (98gr. @ 750 fps) more powerful than the .32acp (71gr. @ 900fps).

JERRYS. · December 4, 2017, 08:35 AM

Cosmodragoon says it al right there in post #10.

I would first look to see what the gun's manufacturer says about the model's capabilities. I would then want to know if the gun's springs have been changed, creating a lighter primer strike.

Using standard math the difference in energy is less than 5 ft/lbs... that's so minute they're essentially the same power, but given the .32 S&W bullets are heavier, they will penetrate deeper and because of that, I consider them more powerful. The one Buffalo Bore load I linked to is pretty much the only .32 Long ammo that is statistically more powerful than .32 ACP. Yeah, it's not as cheap, but no Buffalo Bore ammo is. Point is the .32 S&W Long has the potential to have more power than the .32 ACP if it is loaded correctly.

When it comes to the .32, because they're so weak, the name of the game is penetration.

However, if the OP is looking for the best defense ammo in .32 Mag, the Buffalo Bore .32 Magnum load that hits 300+ ft/lbs is it. I would say that compared to what Hornady and Federal offer in .32 Mag, it's the superior choice.

If penetration is the desired effect, the underwood captivator seems a good choice given the results of this youtube gel test:

Underwood offers this in .32 acp, but not .32 long.
Considering carrying this in my seecamp, but found that occassional rounds have too hard a primer and requre a couple of trigger pulls to ignite. They feed and function fine otherwise. I like results I saw on the video.

Pathfinder45 · December 4, 2017, 01:32 PM

The cost of factory ammo for all of you 32 caliber shooters is irrelevant because you all either reload your ammo, or, you have deeper pockets than I do. If you do not reload your ammo, you would be far better served with a 38 Special or 357 Magnum for sheer availability of ammo, even if cost doesn't matter to you. If you do reload stock up on components. And use the right ammo, for goodness sake.

try to compare apples to apples. look at BB 75gr. .32acp loading if you're going to use them as your argument for the .32 S&W Long.

Actually, 900 fps with a 100 grain bullet if you buy the right ammo:

And the 32 Auto is more powerful if you buy the right ammo:

https://www.buffalobore.com/index.ph...t_detail&p=132

According to SAAMI nominal specs, they are roughly the same.

32 S&W Long; 98 grain at 775 fps = 131 fl lbs ME

32 Auto; 71 grain at 900 fps = 128 ft lbs ME

That's cavitator, not captivator.

Power and Penetration are two different things.

Every time you make up crap comparisons you're going to get flak over it.

T. O'Heir · December 4, 2017, 02:50 PM

No. The .32 ACP headspaces on the case mouth. You'd have .395" of excessive headspace. The ACP's semi-rim is .358" diameter vs the .375" of the H&R. The ACP's diameter at the case head is .338" vs the .337" of the H&R.

That's expensive ammo, as is the BB .32 Long, but unlike the .32 ACP, the .32 Long BB ammo can be shot in a .32 S&W Long revolver, while the .32 ACP would be potentially dangerous.

So, you're getting an ammo that's virtually the same power or more and is safe to shoot all day long.

The argument is irrelevant as this thread is about .32 H&R Magnum and any .32 H&R Magnum is more powerful than either .32 ACP or S&W. Average .32 S&W Long LRN vs average .32 ACP FMJ is virtually identical, with the nod to .32 Long because the bullet is heavier and penetrates better.

Now, instead of hijacking the thread to point out that you think I'm wrong with my statements, lets keep building on the OP's topic at hand.

OP, what revolver is this? This will help us determine whether or not .32 ACP is a good and safe ammo to shoot in your gun.

2damnold4this · December 4, 2017, 04:24 PM

If you want to shoot .32 magnum on the cheap, you could reload some full or semi wadcutters.

Never thought we would get in an aurgument over the 32acp vs the 32 long.

I reload for both and from a 2" barrel with longs shooting a 94gr bullet I get just over 850fps. Does it beat the 32acp? Heck if I know. I didn't buy my 32s because they were power houses.

The biggest problem with shooting 32acp from a revolver is the undersized bullet isn't accurate. The 32 long should be between .3125 to .314. The 32acp is loaded with .311 bullets.

For some strange reason most guns shoot best with the ammo they were designed to shoot.

Use the search function and you will find there are bunches of threads about doing this.
