I've put a few lbs through some of my military rifles with cast bullets over the years. My best accuracy load in my 03A3 is Lyman 311291 over a mid range load of 2400. Have had good success in 8x57, 6.5 x 52, 7.62x54R and 303 Br as well . Only negative comment I have is I experienced a couple hangfires in 3006 with starting loads. Some gas leakage in most calibers with starting loads as well. Doesn't seem to be position sensitive with heavier loads. Kind of replaced 4198 as my favourite cast bullet powder.
