You're going off track now. Find a round it likes and don't deviate. Mixing and matching will only bring you pain and suffering, as well as internet scorn. Ditch the FGMM 168s and go with the 175s, they will handle transonic better.I'm looking for recs for cheap practice ammo. I've already been recommended Federal 168 MatchKing for the "good stuff".
Does anyone have experience with Igman 147gr?
