Bear in mind this is a .458 Win load not a .458 Lott.
71 grains of H4198, 215M, Norma brass. I could go higher and did, but the accuracy went downhill. In addition by staying at 71 grains it shoot to the same POI as my 450 grain A-Frame and 420 Safari Raptor loads. They all shoot together out to 200 yards.
