It sounds like it would be a blast to shoot. I have a Heym .500 B.P.E. rifle with hammers and a Jones under lever. It's a back action and fun to shoot and amazingly accurate for an iron sighted rifle. I hope to take a deer with it.
I have a line on a couple of Parker small bore but the jewel in waiting is a 16ga CHE that's got probably 80% case color, 30 inch barrels, PG. SPF. A really nice gun.
My daughter is getting married the end of September and that's not inexpensive
