Because your fired bullet is smashed, we need super-precise measurement (in 1/100ths-of-an-inch) of the diameter of its base, to figure out your bullet's caliber. We also need precise weight measurement, preferably in grains but at least grams. (Impact-damage changes a bullet's shape but not its weight.)
Although your fired bullet somewhat resembles a civil war era Sharps Rifle/Carbine bullet, the body-groove above its base it too deep for a Sharps. The white oxidation on it suggests it is a pure-lead bullet, which was most common version until "about" the 1880s, rather than a lead-alloy bullet, which is the standard for 1880s-through-20th-Century bullets. I suspect your bullet will turn out to be from a few decades after the civil war.
Thanks for the info Cannonballguy, I will see if i can get some measurements and weights.
this was the first think i pulled out of the yard, hopefully i can find more.
