.32 ACP Rifle Chamber Insert

[RED]

The insert I have was developed to poach deer at extremely short ranges. It was supposed to be better than a .22 and quieter than a normal .30 cal. BTW I do all my poaching in the morning...

... eggs that is.

When I was a child I was listening to a discussion about the best deer cartridges. One guys said "as many deer have been killed with .22 shorts as anything else."

Of course back then people poached for meat, not horns, which I'm sure contributed to a higher number of poached animals before, lets say, 1950

chamber inlets are a little like gay marriage...not quite what the good lord intended.

I've got one of these beasties to allow .32 H&R Magnum in .30-'06. In my sadly bubba'd Arisaka, accuracy is a joke. I think the bullet rattles down the bore, and produces keyholing at 50 feet. (Yes, feet, not yards.) I'll not be tempted again by anything similar, but it is an attractive proposition, eh, what?

The Arisaka is one of those butchered with a .30-'06 reamer run into the Japanese chamber. It's not entirely safe for full-house .30-'06, and I thought to at least get some use out of the rifle. No such luck.

Hey Guys, nubee with a question here.

I have an Arisaka, Type 99, which is still chambered for the old 7.7X59 Jap round. The stuff is hard to find and very expensive as some of you already know. I came across these inserts in one of the catalogs and was wondering exactly how they work. It seems as though some are glued into the chamber while others look like they are meant to have the smaller round inserted into the insert and and then the entire thing is extracted after each shot. Am I correct here or just confused?

I don't intend to hunt with this rifle just take it to the range and do some plikin so being able to shoot something easier to come by and less expensive like the 7.62X39 would be great. Some of you have touched on this already but what are your thoughts on doing something like this? Is it worth the money to have one of these inserts custom made, I can't seem to find one for the sized for the Arisaka, or is it a total waste of time and money?

Thanks,

Scott

The neck area of the adapter probably swages the bullet down to .308.

You might be able to salvage something by reaming out the neck of the adapter to .312 or so.

The type of adapter under discussion here is not glued into the chamber. It is a steel sleeve shaped like the original rifle cartridge, but having a smaller chamber at the back to take a pistol round. When the round is fired, the adapter is extracted and ejected like a fired case. The fired pistol round is pried or punched out and a fresh round inserted. (There is another type of adapter, which allows a .308 round to be fired in a .30-'06 chamber; those have been used even by the military, but proper installation involves epoxy and rechambering, making the conversion one way. I don't know if there is a 7.7 Japanese to 7.62x38 adapter or not.)

The pistol cartridge adapter made sense when rifle ammo was expensive and pistol rounds cheap; I am not sure it would be practical today, and light loads for plinking or varmint shooting would be less expensively obtained by reloading the rifle cartridge.

Incidentally, .32 ACP bullet diameter is .312, not .308.

Had a 32ACP / 30-30 adapter for many years and put many rounds of 32 out that old 30-30 without any problems. Like was said earlier , original intent was for a cheap, quiet meat maker. This rifle was made in Chicopee Falls back before they needed to serial number them . It has been in my family since as long as anyone can remember,they say Gramdpa put alot of meat on the table with it. I was told the 32s were much cheaper than 30-30s back then and easier to get. One Uncle told me it was mail ordered new back in 1920's or 30's from Sears(rifle and chamber adapter). Grandad and his 9 brothers came to Wisconsin in 1884 from Denmark and homesteaded several farms around what is now Dorchester. So you know they had a taste for venison, and cheese,(beer too).Point is that chamber adapter ain't no new idea.

I've never owned a .32 ACP, and my first reaction was that you are wrong.

I then checked a few sources (old, but still on the shelf) and found a spread:

Lyman cast, .309; Hornady, .311; Sierra, .312.
