I just obtained a old Marlin 1895 .45 -70 in trade from person I did some fence work for. I say old because it doesn't have that ugly cross bolt safety on it. I thought about maybe taking it to the deer woods here in couple of weeks, and I was wondering what type of load would be appropriate for the thin skinned white tail. I know that the .45-70 packs a wallop, but how severe is it from an approximately 7 lb rifle with a 22 inch barrel?
