Subcaliber inserts.

Anyone with a lathe and the knowledge to operate one, plus a reamer should be able to fabricate almost anything that makes sense.

How would that work? You still have a .45-caliber bore.

A barrel insert? If somebody necked down the 45acp to .358, that would be easy to make a conversion for a 35w rifle...

See my last post at the bottom of the page here:

The .22lr one in .45 colt *sorta* makes sense for a .22 shotshell, but not a bullet. Still the problem of the rifling spinning the shot, however.


Some of the ones that make the most sense:
.22lr in .22 magnum

.22lr in .22 hornet (don't know how they do this one)
.22lr in .223 rem (ditto)
.22 mag in .22 hornet (ditto)
.22 mag in .223 rem (ditto)
(if those are offset to get the firing pin to strike the rim, then how is the bullet centered in the bore??)

.22 hornet in .223 rem or .22-250 rem
.223 rem in .22-250 rem

.22 lr in .410 bore, 20 ga, or 12 ga (for .22lr shotshells)
.22 mag in .410 bore, 20 ga, or 12 ga (for .22 mag shotshells)
.45 colt in .410 bore, 20 ga, or 12 ga (for .45 colt shotshells)
.45 acp in .410 bore, 20 ga, or 12 (for .45 acp shotshells)
.38 special in .410 bore, 20 ga, or 12 ga (for .38/.357 shotshells)

.410 bore in 20 ga or 12 ga
20 ga in 12 ga


7.62x39 in .308 or .30-06
.32 acp in .308 or .30-06 or 8x57mm
.30 carbine in .308 or .30-06

(I don't think you could do .30-30 win in a .308 or .30-06 could you, due to the rim on the .30-30?)

how about shooting 221 fieball in a 223,I like to have one,,

22lr in .22 hornet (don't know how they do this one)
.22lr in .223 rem (ditto)
.22 mag in .22 hornet (ditto)
.22 mag in .223 rem (ditto)

PremiumSauces, these will work in a T.Contender as they have 2 firing pins and a rotating block in the hammer. You can select rimfire or centerfire.

MCA made inserts and adapters that covered many on your list, but they no longer have a website.

Just found these funky inserts.

have seen many pistol-to-rifle converters. One reason I love my .35 Whelen is that I can handload .357 pistol bullets in it, for quieter, less zippy practice or plinking loads. But I got to thinking: what of caliber conversions for it? I don't suppose that a .38 Special revolver rim would fit in the base of a .35 Whelen (read: .30-'06) case. But I would think that one could be made up for .357 Sig, which is rimless.

I think the rim diameters are still similar. Let's see. 0.422" rim dia for .40 S&W (nickel plated Speer), 0.435" for .357 mag (Winchester). Not that much difference. .30-06 is .470", so I think .38 SPL might work.

Hm, MCA must have gone down recently. Their website was still there as of 2 weeks ago. I guess it may be a good thing I didn't place an order.

Wish I could find someone to make my 3-shot .22 to 12 gauge adapter idea. Use rifled barrels and it could be relatively accurate.

Interesting concept RyanM, although I see no dimensions to verify. The method of securing the capping/firingpin part for easy access and alignment needs to be addressed.
I would suggest a one piece cap with a single metal piece of round stock for a firing pin, large enough to fire all barrels at once. I'm just not sure if a shotgun would impart enough force to the large pin to fire the 22's. The one piece cap would use a simple O ring to secure in the body and would not need alignment.

Simply using a section of 22 barrel liner would work for the barrels.

At least it's fun to dream about such things.

For anyone interested, here's another site that has adapters.
I knew I had seen this site before, but it wasn't bookmarked.

A Better Idea

The Hammond Game Getter is the best for my money.

http://www3.telus.net/gamegetter/

The Game Getter is essentially a standard case with a steel head and an offset "primer pocket." The primer pocket is really a chamber for a .22 RF, positioned so the centerfire firing pin will hit the rim of the case.

The Game Getter comes with a sizing die which you use to size buckshot to the appropriate caliber. In use, you insert a Ramset (tm) blank in the chamber, a sized shot in the mouth of the case, and fire away.

I have one in .30-06, and the shot impacts at the thick top of the bottom crosshair at 25 yards, producing 1 inch groups. It's ideal for deer hunting, when the squirrels try to carry you off your stand.

Hammond Game Getters are available in all standard cartridtges, and for wildcats, if you send Hammond a case he will make one up special.

The 3 shot .22 would fall under NFA regulations. There is a comapny that makes something similar for 37 or 40 mm launchers its called a beehive and fires either 10 or 18 .22 at once (i can't remember)

I am waiting for someone to suggest using a 26mm flare to 12 gauge adapter then a 12 gauge to 9mm adapter so you can get a 9mm single shot without any paper work

Anyone know of someone making such conversion sleeves in .357 Sig to .35 Whelen? Or even 9mm to .35 Whelen? .38 Super?

Click to expand...

I'm not a gunsmith, but wouldn't .35 whelen pressures in a 9mm destroy the gun, and possibly it's user?

I've had these for many years. I mentioned them on another thread. They have about 1" of rifling and I use lead only, 250gr@1100fps inthe 44 mag. 148gr wadcutters in the 357 Mag. Both will keep 2-3" group at around 30yds out of my rifle sighted single barrel 12ga.

oldgold, that link is no good...which one did you mean to post?

If you get Shotgun News there was a fellow from Alaska that made all kinds of sub caliber inserts just can't remember his name off hand.

When was the last time you saw an M203 or M79 that was registered as a machine gun? The ATF's ruling is that a single cartridge can shoot as many projectiles as you want (i.e., buckshot, birdshot), so long as it's a single cartridge. A bunch of .22s loaded into a beehive round become a single cartridge, since the whole thing is set off by one primer. Same for my design.

It actually is dimensioned, 1 pixel = 0.005". I was just too lazy to put them on.

Anyway, I really doubt that a shotgun firing pin would have enough power to fire 3 .22s at once, plus there's the legality thing mentioned above. It may be that it'd still be legal since they're all in a single cartridge, but we already know that primer-actuated designs are legal.

Alignment would just be by 3 protrusions on the walls in the part of the adapter that holds the barrels, which line up with 3 slots on the firing pin whatsit (the red part).

Actually, though, you may be onto something. I bet a primer would have enough punch that a simple one-piece firing pin could whack all three.

Well all 40mm grenade launchers are NFA, and 37mm flare launchers become NFA once you load with anything besides flare or smoke. Your device would become NFA because it fires 3 shots with a single trigger pull. I agree you can fire multiple projectiles from a single cartridge, not multiple cartridges. I am not sure why you think loading 3 cartridges into a single larger device qualifies the device as a single cartridge. They are still 3 separate cartridges. You would be firing 3 shots with a single trigger pull (a machine gun).
Notice I used NFA to describe the device. NFA is not just machine guns, it could be DD, AOW, SBS, SBR, silencer. So 40mm and 37mm anti personnel are NFA because they are destructive devices.

"NFA" is not a simple, black-and-white catch-all classification. You cannot register an AR-15 as a short-barreled rifle, then go ahead and install an auto-sear.

Likewise, you cannot buy a destructive device and turn it into a machine gun, nor can you buy a machine gun and turn it into a destructive device.

The ATF's ruling that a "beehive" round is a single cartridge may not make any sense, but how many of their rulings do?

NFA classifications basically have several tiers. An NFA weapon may have features of lower tier classifications, but not equal or higher tier ones.

In the top tier are machine guns and destructive devices (also silencers, I guess). There are also a few weapons which are both a machine gun and a destructive device, like full auto shotguns and grenade launchers, but those would actually be entered into the registry twice, under both classifications (though you only fill out the paperwork once).

The second tier is short-barreled rifles and short-barreled shotguns.

The third tier is AOWs.

In other words, a machine gun may be made into an SBR if you want, because machine gun overrides short-barreled classifications. But you cannot rebarrel a machine gun into a caliber greater than .50, since then it would be a destructive device as well.

You can take a registered destructive device and cut the barrel down so that it's an SBS or SBR. But you cannot put an auto-sear in and turn your destructive device into a machine gun. "NFA" does not mean "I can turn this thing into any kind of NFA weapon I want." If that was the case, everyone would be selling parts kits to build a machine gun on an M79 or M203 receiver.

Also, mcace.com is back up, hooray. I guess they didn't go out of business after all.

I can see this has derailed like AMTRAK under ideal conditions, nevermind.
