Help in identifying shell from frag found

[Ripcon]

The shell frag was found in an area where both Union and Confederate projectiles were impacting. It was in a field which accounts for its degraded condition. Any help is appreciated. Thanks!

Light Burrellet is around the top of the shell. Maybe a 10 pounder Read??

Hello.   Hard to say from the pics.  If that is a bourrelet as Ripcon asks then it would be narrowed down a good bit.  Also the fuse hole still contains crud but if you could get a thread count and approximate diameter that would go a long way to narrowing down what it might be too.
