Would it be possible to convert a 336 to 10MM?

[alwaysshootin]

I'm thinking, I would love to have a lever action 10MM, and can't think of a better platform to convert. Of course, if this were to be stupid expensive, I'd go another route. Love the 30/30, but what I do with it, I could do with a 10MM, and that's accurate shots, on whitetail, < 100 yards. Would love to hear your input!

the 30-30 rim is significantly larger than the 10mm.  An 1894 in 357 Magnum would probably make a better starting gun as the rim diameter is much closer.

I wrote both Ruger and Marlin about producing 10mm rifles.  Ruger semiauto rifle in 10mm like those of the 44Mag and Marlin about producing the Camp Rifle in 10mm.  Small compact carbine style guns that would be great platforms for the cartridge.    Their response was like they weren't interested... :'(

Despite how much sense this makes, it is definitely a do it yourself proposition.  I found green mountain barrel blanks a few months back and they are quite reasonable.

I would love to see something like the camp carbine or deerfield carbine in 10mm.  I have also read of guys converting M1 Carbines to 10mm.

I think a 10mm Tommy Gun would be a big grin winner too!

I don't think the 336 would be a good candidate.  The 336 in .44Mag was discontinued because the action was finicky with the short pistol caliber.  I would give a long, hard look at the possibility of using an 1894 instead.

Truth be told, it was just a thought. Not to mention the 336 just doesn't see much use these days, but I'm not getting rid of it. If I had a 1894, I'd consider it, but I don't. Buying any firearm, and then converting gets quite costly!

Yes it does.  I figure I am looking at a couple hundred plus the barrel to get my carcano shooting 10mm if I decide to take that plunge.  Good news is it comes in small chunks.

A bill of a couple/few hundred, wouldn't slow my thinking down. It's the ger + that leaves me with my mouth agape thinking, this is a bad investment! Mind you a bad investment into something way up on the 10MM cool scale is ok, but dag a grand? Have to go another direction.

That is one benefit to converting a bolt action.  Pretty much just have to pay to have the barrel turned and headspaced on the action.

I have one in development now, after a couple years of just dreaming about it.  My intentions are similar to yours, except with mulies instead of white tails, big cats, coyotes, perhaps black bear, and of course, it sounds like fun.  We'll see where the performance lies.  It should be off paper by Summer's end, then a working prototype mid-late Winter.  Affordable CNC time is hard to come by.  The base rifle is planned on the W1992, with a possibility of a pre-64 W1994, both carbines.  Finding modestly used rifles is proving to be a real chore.  They're usually all used up, or too purdy to mess with (collectors = $$$).  Not much in between.  I considered Marlin (which I like), but they don't like short rimmed cartridges, and think a rimless would be worse.  I'd like to share more details, but can't just yet, with several patents involved.

I checked a few common calibers, but the rim diameters were all 1-2mm larger than the 10mm.

You might be able to trade your shooting 336 for an 1894 with a rotten barrel.  Actually, I'm trying to do just that so I can have one in .45 Colt.

I'll tell ya, guys.....  If it were only a matter of having a barrel cut, I'd be done a year ago last Thursday.  And cheaper.  Unless you're building a single shot, it goes a lot deeper than just that.  The 10mm is relatively short, narrow, and rimless.  How's the .38/.357 rifles working out?  I've had several, repaired several more, and the story is alway same.  They shoot wonderfully.  That is, if you can get a cartridge to the chamber.  94AE's have a long list of their own issues.  Subtract the rim, and the only remaining saving grace is gone.  Gotta start from scratch, almost to the drawing board.  It's not really that bad, but it's starting to feel like it.

A 10mm bolt gun could be fun and keeping the brass would be easy. What would be a good action for such a project?

[sqlbullet]

Carcano.  They can be had cheap, the bolt face is close enough to work at .450" versus .427" for the 10mm.  Chances are you could continue to use the existing en-block clips and it would feed fine as it is a controlled feed action.  In fact, single loading is bad for the Carcano action.

You might be able to re-engineer the trigger guard/magazine to be a mag well for a different magazine if you wanted more capacity, but the en-block's work pretty well.

They have or "Had" the 10mm Tommy Gun.  A guy had one at the range about a year and a half ago.  A real jam o' matic.
