Before I begin, this question was posted on George's forum. So if it familiar George. It is.
I have been kicking around the idea of a scout rifle in 45/70 built on a Mauser action. I have built a number of rimless cartridge rifles on Musers, but never a rimmed. I have a few questions that I would like to put out for comment.
1) is this idea do-able?
2) How would one slot the back of the barrel for the extractor claw. WOuld this be done similar to the extractor notch found on WInchester rifles?
3) The base of the 45/70 rim measures .620 in diameter for a radius of .310". A Mauser magnum bolt face has radius of .269" from firing pin hole to bolt face rim, +/- .004". Turning the bolt face rim for the 45/70 case would leave precious little material left to hold the cartridge straight. Does anyone know how much would be too little?
4) I am assuming the 45/70 headspaces on the case mouth. Again, I have never cut a chamber for a straight walled case. The case rim should sit flat at the breach when properly reamed? We will worry about the chamber throat if I get that far.
Like I said, this is just an idea that i have been kicking around. But your input would be appreciated. Thanks.
