Here's my experience with a T3 Lite SS in .308.
Laser bore sight scope.
Take to range and fire shot onto paper.
Re-zero from that shot.
Put three into an inch at new POA.
Go hunting.
I haven't even attempted to work up a handload yet or try another brand of ammo. Damn thing simply puts bullets where you aim it. I guess at some point I need to see what it "can really do" just for giggles but as my new favorite all-around deer rifle it's got nothing left to prove.
