I bought a Marlin 38-55 a couple years ago and didn't do much with it till lately, I bought brass from rusty wood, I just measured it and it is 2.080" I don't know much about the Marlin it was an impulse buy! On the barrel is "Black powder", so I guess it is older, looks to have been worked on, reblued I think and someone put a Williams's peep sight! Does anyone know if I can use BP replacements with this barrel?
