Thanks guys, I appreciate the info. I bought the small base die set yesterday. I have not tried to re-size any brass with it yet. Is is possible to just do a PFL sizing for an AR. That is generally what I do with my bolt action rifles and get excellent accuracy. The reason I bought the small base die set is because my buddies say that's what they use. I want this one to be very reliable with no hang-ups. Thus far after shooting it at the range, I am tickled pink. Everything went exceptionally well. I will say that I believe the rifle shoots better than I do. I'll post some target pics later. All is looking good though, considering I was using brand new brass that was already primed with CCI400's that I was going to be using in my bolt rifle. I scored on a bunch of BR4's that I'll be using in this once fired brass next go around. This rifle is exactly what I was looking for and at a price I couldn't pass up. I think I'll be happy with it. Thanks for the response to my questions.
