Would I be tooting my own horn to mention that I have a ten bore double rifle?

Colin Stolzer built it for me when he lived in Kansas.  240gr of Fg and a 750 +/- grain acorn shaped RN.  Hammerless side by side of course.

I have shot a four bore.  Twice, both barrels in 15 seconds.  Ken Green in Carbondale, IL had one of three that Ken Owens of Memphis fame built.

It's probably why I am a bit rummy...

I'm late to this thread but, I can't help responding to this one.

In the mid 90's, a good friend, that was a high end collector and shooter, invited me over to get my advice on how to repair a gun part. While there he asked if I would like to shoot his newly acquired 8 bore double. I said no, that I didn't care much for recoil! He said that he had been shooting it with reduced load and insisted I shot it so, I said ok.

He set up a 26 oz coffee can to aim at. Pictured is the result. The load was 250 gr 1F and a 1080 gr bullet!!!!

He took a big chance, as it was a engraved double that I think he payed ~$5000 for. My first thought after pulling the trigger, was to get away from it asap and that would have included dropping it right there. But, he was lucky, in that I didn't.

I wasn't very happy at the time but, it did result in this trophy

Colin and I talk about once a month.  He is still building big bore muzzleloaders to order.  His last four bore double percussion rifle he built for a customer had a companion single shot pistol.  He was in Kansas on the family homestead (Civil War soldier ancestor) for many years, but decided to move to the Powell, WY, area where he worked on the oil fields for a decade and learned the machinist then gunsmith trade.
He built me a medium bore bolt rifle, can't remember now if it is the 404 Jefferys or the 425 WR in the safe.
