    I don't normally do things like this, but I have found a project gun and need to know it it looks doable. The rifle is a 91/30 with a 45/70 barrel on it. According to the seller it will need a modified magazine to accept the 45/70. It may need work on the feed ramp to get the 45/70 to feed.

    Instead of modifying the bolt face to accept the 45/70, his idea was to modify the 45/70 case rem to fit in the bolt face of the 1891. That sounds like too much trouble. Would it be possible to modify the bolt face to accept the 45/70 case? There's not much metal to grind off on the bold face. Would it be possible to get a magazine from another military bolt action that would accommodate the 45/70 round and be made to fin in the 91/30 stock?

    Does this sound like something that can be salvaged for not too much additional money or is it a hopeless mess?

    Thanks.

    The issues with the magazine is why the seller sold it. You might be able to make it a single shot without a lot of investment. Do you know if the barrel is properly installed and headspaced?
    Mosins work best utilizing a wildcat based on the original case.

    The barrel is supposedly headspaced correctly. I would take it to a gunsmith before I did anything. Can the bolt face be made to accommodate the 45/70 rim? It looks like the rim is too wide to fit.

    I'm planning one in .348 rimless. I'll be turning & thinning the .348s rim to the Mosin's rim diameter & thickness and then adding an extractor groove. I'll use a case sizing die in my lathe to hold the case for turning. A hundred or so cases will likely last my lifetime, so it's really not that big an inconvienence.

    I converted a Mosin Nagant to 45/70 in March 2003.
    I have just shot it single shot.

    I ground a little tool to get into the bolt face and open it up.

    Its not that hard to have a machinest make a new bolt head for those mosins to the proper dimensions of a 45-70 rim probably lookin at 50-80$ for one to be made
