thats looks great, you better aneal the case mouth of the magtech brass. have made similar crimps with 12 ga brass once and most splits with first shot. maybe your lot is softer now.
your target is very, very improvised like deep in the woodland but it show that the mysterious straigth rifling isn't useles at all. your husky is worn but with character, any signs of old colour case on the action?. I would reblue the barrels and rework the stock careful
dont know if all old husky have had colour case on the action like my 17 A in 16ga - 24/40 here

another one was high polished
