Finally got my new bps sighted in today.It has a C-N-C tube and a nikon turkey pro scope.Tried 3 different loads through it,turkey thug 5s and 6s and win 5s,at 20yds there wasnt much difference in any of them but moving out to 40yds the turkey thug 5s shot the best group.The 6s were next but the win 5s just opened up too much.
