The powers that be are interested in our team getting a 50 cal. Had one of the State team guys bring out thier Barrett. Older gun, bullpup bolt action, I think they got it in 97. Ran about 2 min groups, with an off brand of ammo. I understand the AI verion is a lot more accurate, but we were leaning towards a semi. Any experiences with the 50 please chime in. Also interested in ammo. What shoots good and what should we stay away from. Not going to be handloading, just buying factory stuff. Primary use is for stopping or shutting down vehicles.
