Hi All. I’m new to BPCR and in fact just picked up my first rifle at auction. It was listed as a “European 50-70” without any other info. I’d appreciate any info (manufacturer, age etc.) that anyone can provide. I haven’t slugged the barrel but calipers show approx 12mm lands and 13mm grooves. The tang markings are difficult to make out in the photo but appear to read “Remington Ilion NY USA, PAT May __ Nov 15th 1864 April 17th 1866”.
It was suggested on FB that it may be a Swedish 12.7x44R. If that’s the case I have questions about the possibility of using 50-70 brass and bullets. As far as I can tell, it chambers and ejects 50-70 brass appropriately. The close up of the closed action is with a casing inside. As I mentioned, I know very little about BPCR so I very much any help!
