It just hit me, we dont have a brag board for groups from our 450's! I just thought of it because i've got a group to brag about. I've been playing with the Barnes 200grn Xpb. I've definately found the sweet spot for my rifle. Now i've just to get some more loaded up for deer and the chrono. This is a 5 shot group @100yds. I didnt think all 5 were in there but the backer board revealed no other holes!
