Converting a Rossi '92 to 38/40

(1/3) > >>

Black River Smith:
If I wanted to convert a Rossi '92 to 38/40 what would be the best 'rifle' (not carbine) to start with? A 357Mag or a 44Mag?

In my opinion I think the 44Mag would be better for the bolt face and extractor/ejector size, going from 44Mag to larger 38/40 rim diameter.  But the cartridge guides would be to large for the bottle neck taper. ???

The 357, I think the bolt face would be too smaller? and the extractor/ejector too?  Is the 357 frame smaller compared to the 44Mag?  The cartridge guide would have metal that could be cut though.

Do 357 cartridge guides fit into the 44Mag frame?  If so, then they could be purchased and recut for the 38/40 profile or is this an incorrect idea?

The 38/40 and 357Mag cartridge rifles are ones that I have never owned or shot.  Would like to have the 38/40 most, of either.

Comment are appreciated.

No gunsmith here, but I'd think that starting with one in .45 Colt or 44-40 would get the bolt face, extractor and ejector closer to the right size than either the .357 or .44Mag. And the magazine tube would work better, too. Do the .357 ones have a smaller mag tube on the Rossi? I think the original '92s had 2 different mag tubes, one for 44 and 38, another for 32-20 and 25-20.

Black River Smith:
Pony,
Thanks for the reply.  I did not even think about the 45Colt.  The bolt would only have to be modified slightly to reach the 38/40 diameter.  Also did not even factor in the magazine tube size.  Really thought the 44Mag and 45Colt and a 44/40 (that they use to offer) would have the same size tube.   

This is why I asked here.  My general focus has been of the cartridge guide rails.

If a 45Colt barrel was used, are liner diameters large enough to fill what diameter has to be cut out?

Hey BRS ,, Paul Taylor , did the reline on my 92, ( it was already done when I bought it ), it was a 45LC, can't tell it has a liner. But the cartridge guides on ea. side,
 ( where the base of the case fits )have to be moved forward , I took my 92 Rossi carbine apart and used it as a pattern ,, works slick,, the opening in the frame where the mag. fits, needs to be opened a small ( small )bit as the 44-40 & 38-40 have a bigger base dia.

 If I can help ,,, just holler.

Only one choice here - 44 mag - all ya got to do is rebarrel and go shoot - cartridge guides maybe need a lick taken out of em but I know for sure that 44/40 guides will feed the 38/40 without alteration - case rim is identical extractor / ejector same -- if you use 357 you got a lot of stuff to change .
