yes 308. scope is night optics d740. i've had it a long time and still like it a lot. texas allows lights, lasers, night scopes, just about anything for non-game animals. not sure which hogs you're talking about, but they aren't as big as they look. putting the camera on the ground and close to the hogs makes them look big. i don't think i've shot anything close to 300 in several years. most that look big are probably 175-225, but i don't weigh them anymore.
