I went to the range this morning, with my .223 just to get it on paper, I used 53gr VAX and 21.5grs. of H4198 my first 5 shot group had a flier but still measured .504 at 200 yds 3 shots 1.022. My next trip will be with 69gr Sierra, and Varget. My only complaint is after firing a round I would put another round in the chamber and close the bolt but couldn't move the red blade on the Accutrigger. When I lifted the bolt I noticed the red blade dropped down them I was good to go. The cases were FL sized the bolt closed easily this happened on most of the cartridges. It never happened on an empty chamber. Any one ever have the problem. thanks Bob
