Yesterday s finds maybe a 3 ringer??

[Mark kus]

I was out detecting along the Thames river and found a hill with what looked like old fox holes about 4 the whole site was littered with iron..
I pulled a old rim fire casing and a fired bullet looks like a 3 ringer? As I never find any 3 ring bullets here in Ct .
Maybe you guys can identify better both?
Thanks
Mark

Cant see a primer so a rimfire case I’m thinking, cant tell mouth diameter……. No idea on the bullet, thats foreign material out my way!

I also think it is ring percussion, but I don't know of such a large ring gauge

My guess is an early black powder rimfire based on the straight walled case. first guess would be a 45 70, post civil war and very popular out west although used throughout the US. Looks like it hit it's mark.
