Home Forums Hunting & Shooting Savage Collectors New toy: Marble's cartridge adapter 22 HP to 22LR

Very cool!!! I was a huge collector of all things Marble's till this sight runied me, sold most of my knives and stuff to build rifles. I have seen only 1 of these before, rare is an understatement.

Please let us know how it works.

I would think that it would have to, the 22 LR case is the same diameter as the bullet and has to have a sleave around it to fit the neck area of the chamber. The 220 Swift is listed with a larger neck diameter (.260) than the 22 Savage (.252) Looking at the list I would have to think that #150 and #151 may also have to be like this because the 32 Short Colt has a heeled bullet with the case the same outside diameter. Both the .30 Remington amd the 30 WCF list a .328 neck diameter and the 32 Colt case is listed at .318 - which might be close enough. I see all the other 32 adapters use 32 Colt Automatic or 32 S&W which have larger diameter cases - bigger than the neck size of the 30 WCF and 30 Rem.

as to .22hp bore dia., a while ago i tried to find out that very thing and it's like it's a nat'l. secret. i finely found one source that listed it at .221. if this is incorrect, i'd like to here about it.

Howdy - I have a No. 161 Marbles adapter, the hole in the side is just to pull the extended firing pin out since it has a little spring device on the side of it to hold it snug in the cartridge. Good luck finding that little bugger if it falls out in the grass! Mine still has the little 22 steel plug in it that you use to keep it stored with so the end doesn't get smooshed. I was thinking of making one out of a used brass cartridge and then machining a new extended firing pin. Do any of you know of any reason why that would be a problem? Just concerned about pressure, I certainly don't care about ruining the brass cartridge but I don't want to damage my 99.

dkgenned1, 22hp bore diameter was .227 - slightly larger than the standard .224, though a lot of reports say that standard .224 bullets work well in most 22hp's.

This is a 220 Swift adaptor.

# 170 250-3000 Savage/25 Colt Automatic


This one would be neat to have.

I have the 22HP adapter and have seen the 303 a few times but have never seen the 250 adapter... that would be pretty cool to have...

Winchester branded some called Supplemental Chambers, I had a whole box of them and was quite suprised what they brought on ebay.
I had one for a 303 and shot it, witha src, the only 303 I've ever had, single shot, a little boring,

Ya aint got no imagination boy...

Well, I tried it, the Rugers shoot handy 10 to a clip

Fifty if you've got the right magazine.

Here's a picture of the Winchester adapter for the .303 Savage, on the left. The other three are Marble's adapters in various chamberings. The Winchester adapters were chrome plated and pretty nicely made.

Don't know if anybody here will be interested, but I just listed a Marble's #174 adapter (for shooting 22 long rifle ammo in a .220 Swift) on eBay.

Dad purchased a new Marbles adapter 22/220 swift in the early 50's. I shot lots of sparrows--very accurate. Rifle stayed out in the corn crib so I could shoot sparrows off barn and then load up .220 swift for stray dogs or pigeons. Made a very universal toy!!

Dispatched a deer caught in a fence with a Model 20 250-3000 and an Marbles adapter. The sub sonic 25 Auto was no louder than the sound of popping corn.

Bought one from Phil, still new in the package, another was gifted to me by an old gun shop owner affectionately known as "Alfie" a member at the gun club who remembered me as a 250 nut.

My 1899H 22 HP was a lot more accurate with 22HP than 22LR at 22 yards. Probably due to the .228 bore.
