My Nova 12ga likes the Cor-lokts. I got the new Hornady SST's for my son's 870 20ga and he dropped a doe three weeks ago with a perfect shot. It went through the left shoulder, and with a very small entry wound, it tore up both lungs and the heart, no exit wound, and no blood trail to follow. I bought some for my shotgun which I will be trying on the range tomorrow. If they shoot as well in my Nova as the ballistics claims, I think I will be shifting to the SST's. I love the Barnes Expanders in my muzzle loader, but the Federals just don't shoot well from either my Nova, or my son's 870.
