I purchased a 45-2.6 a while back. When i received it I took the fore arm off it is a Shiloh that was originally a 45-2.4 crossed out and stamped 45-2.6. After shooting it my brass which is Starline that came with it, OD is .490 and the ID is .468 This ID seemed large to me. I have never Paper patched before,so I was wondering if the chambering is different for this? I have some stuff I ordered from BACO to try. I gave him my Dimensions and he said that he got me as close as he could but it seemed a few thousands small. Can someone tell me what size I would need as far as paped thickness and OD of bullet? Any load info would be greatly appreciated.
