I loaded it in Lapua brass, CCI BR2 primers, 175 Berger OTM wit a charge weight
of 47.4gr (Max in Alliant data is 47.7, so approach from below) I was getting 2740fps in a 24" tube and excellent groups. Does not clean up as good as Varget,
but that was after about 60 rounds in a match.
Good luck cause it gives good performance with 165-180 weight bullets.
