Should work well in most any single shot. I think pressures will be to high for a double conversion but we'll see. Should work in 1886 Winchesters and might work in a highly modified newer Marlin 1895. Enfields would make a good candidate. Snapped a pic while milling and will try to get some if we chamber today. Then I'll try to figure out how to post pics. Been putting that off a while.
