    Any gunsmith can do it. They both use the same basic style of cartridge. So the bolt is the same. Tim

    Does anyone know if the cartridge guides (Model 94 Winchester) are the same for the 38-55 as they are for the 30-30? Apparently the cartridge length isn't a problem.

    The bolt, extractor, lifter and cartridge guides are the same.

    The rim and the lower end of the cartridge are so close dimensionally it doesn't make a difference, unlike the Model 1892, which had cartridges with two different rim and body diameters.

    All you need to do is swap the barrel.

    ----

    To illustrate the point, there are a rare few multi-barrel 1894 takedowns out there. A few ordered a 38-55 and one of the small calibers, like the 25-35, 30-30 or 32-40, often with different barrel lengths. Extremely rare were four barrel sets.

    I had an old shot out Marlin 336 rebored and re-rifled by JES..nothing else needed...I still use my factory loaded 375Win ammo in it for hunting...its a neat caliber especially if you cast your own

    Why not ask where they do that stuff all the time?

    Its a no-brainer really. The 38-55 is a much lower pressure cartridge too. What you do not want to do is shoot 375 Win ammo in it. The reciever is too thin to stand the pressure. 38-55 and 30-30 all operate about 10,000 psi below the typical 375 win pressure. Now, that's in a M94. I have no idea what you can do with a Marlin 336.

    My I sugest that you just buy a used M94 375 Win. It will set you back about $900 if you shop wisely. Then you can shoot 38-55, 375 Win in the same gun. My 375 is a very early pre-angle eject and pre-safety model. The chamber is long enough that 38-55 cartridges chamber perfectly as to the 375 Win cartridges.

    Can you really chamber 38-55 in a 375 chamber? The 375 brass is shorter. Doesn't sound too good for 375 accuracy.

    The receiver around the locking lugs is much beefier on the Big Bore models.

    Just load cast or plated bullets in your 30/30, works great with reduced loads. Trail Boss works well. Berry, Magnus, Widener's carry them.
    Lyman "M" die is the trick for easy loading of cast bullets.

    Brian...you can in the early ones. I did a chamber cas of mine and sure enough, it would work. So, I did...many many times and no problems at all. The early guns have a ton of free bore and they take .380-.381 dia. lead bullets.
