On Wednesday I got a SWEEET deal on a Remington military rolling block in .43 Spanish. The rifle is in nice shootable condition but after my research here in the case forming section and other sites I think I'm going to try a different route. One of the guys I shoot the ram bash with told me I should get the chamber sleeved and then get the rifle rebored to .45-70. Has anyone out there done this? I'm all for a real rolling block in .45-70 as I have a couple of sharps and plenty of loading components. I was looking forward to having a .43 Spanish but a hundred pieces of brass would cost double what I paid for the rifle.
