I have an 87, built in 1891, that came with a "As-Is, Do Not Shoot" label affixed from the shop I bought it from.
As well as a nickel plated, side-levered, hammered 10ga double.
That didn't stop me....
So I order full length hulls from Ballistic Products, pre-primed, Federal or Cheddite.
I made myself a tool that I cut about 3/4" off each empty hull, although Ballistic Products makes one as well.
