Shiloh 44-77 Hartford

Thanks for the info and the pics. I did some scrounging around on the net and ran across a Dan Theador print for a 45-70 PP chamber. I see that you are running the throat taper out to the diameter of the neck area, Dans print was the same way. My thoughts were to do it a little different but it would be much easier to have the taper go right up to the neck diameter. How much difference does the throat taper angle make? Dans print was 25 deg., yours is 5 and I was thinking of something less.
I am expecting a call some time this week from PT&G to talk reamer design and it would be my guess he has an entirely different angle in mind.
My guess also is that the neck wall thickness is another variable that will have to be considered. The case I have is about .0125 thick. If a different case was used to form the brass from it might change that and that could make a difference in things I would think. Waiting to hear back from BACO on that question. One thing I do feel certain about is if the 348 case is used, as thick as that is it should never wear out.
