Shiloh 44-77 Hartford

[Nuclearcricket]

Ok, let me ask kind of a stupid question, inquiring minds would like to know. What makes Orville's pp chamber so good? And does anyone have a drawing of the neck and throat area? I am still flirting with and kind of planning on having a chamber cut in 44-60 bottle neck for paper patch bullets and would damn sure like to get t he best shape on the reamer to start with. I do know that the case neck on the 60 is going to be thicker than on the 77, thats just a given seeing as BACO forms them from 348 brass. The one case I have the neck is about .0125 thick and that will make a difference as to how the reamer is ground.
TIA
