30-30 to 38-55 conversion... anyone?

I am thinking about finding another 30-30 and having it re-bored to a 38-55. I have gotten some conflicting information about the difficulty of the conversion and I am curious if anyone here has done this? from what I have read, (mostly) it's a simple re-bore and re-chamber job and the action will work as-is. I have not bought a gun for the conversion yet, but I am thinking either a beat-up or rough bore Winchester 1894 or 94, or Marlin 336, or 94. Or the cheaper store-brand versions of the same. Has anyone here ever done this? what action would be best?

I've never heard of that being done... is this a nostalgia thing? If you just want a 38-55, I think Uberti makes one. Talk to a good gunsmith though... obviously. It sounds expensive as conversions go.

Simple and straight-forward. Rebarrel and rechamber.

BTW, you cannot use a Marlin 94, that is a pistol cartridge length action, typically chambered for 44 Mag and 357 Mag. You were thinking of the 1893, perhaps?
Never try to educate someone who resists knowledge at all costs.
But what do I know?

JES Rifle Reboring ( ) does them all the time, along with the rebores to .35 cal - for about $245 (today), IIRC.

IDK about converting a Marlin 336, but a Winchester 94 just requires the rebore/rechamber - which Jesse Ocumpaugh does as part of the job.

You can look for a good-used .38-55 barrel as well as doing a rebore. I disremember if it's Numrich Arms or Gun Parts Corp, but they might have one.

I've found good-used Model 94 barrels at the smaller gun shows in New Mexico and Arizona. I was looking for a Type 1 .30-30 at the time; $45.

Cool, thanks for the info. It's actually the JES ad that got me thinking about the conversion, I talked to a friend of mine last night who has a Sears model 45 (Marlin 336c) and with a 20" barrel and pistol grip stock I think it would be a good one for a conversion. Now I just need to talk him into selling it to me! Or find a different one. I like the look and feel of the Winchester, but it seems like the Marlins are stronger, simpler, cheaper, and already drilled & tapped for a scope or peep sight ( I already have a new Lyman in the parts bin) I guess It all depends on what I find cheap sooner.
