I dropped it off at a friends who does reloads.HE is going to get me the measurements. All I have is a tape measure lol.
It is fired so I hope that don't throw the measurements off. If it's not a Wentworth would it be a tower enfield?
I found a couple like that among some minie balls in Va . I didn't throw them out but I didn't look into them I assumed they were post civil war. If theres a chance they're rare keep us posted.
What a great great hunt! I think I might have a fired whitworth also but would take some looking to find it. The whole history of the Whitworth is fascinating. The guy invented quiet a few things. Not as many rifles went into service as I thought but the ones that did.. oh my!
