That sounds very interesting. I am not 100% sure, but doesn't starline offer 50-110 brass? If so, Lancaster may have a great idea. I know at one time it was a black powder cartridge but are there any smokeless loads for it? Is it a fairly accurate round? Will it function thru the 3.1" action?
For the 7.62x54R, I have read of various 9.3 wildcats off of it, but not much larger. Does anyone know of a larger diameter bullet in that case?
What about a shortened NE case that would function thru it?
