I had one years ago. Wish i kept it.
It was found in clay foundation around a home.
It was still loaded. They are good shooters.
They were suspose to be better than the Sharps.
I have a Shiloh also. Try 72 gr. Swiss 1 1/2 .
When i changed over to Swiss Powder i got 100 feet per second faster.
Which means it shoots a little flatter.
