I do cast and have 11 moulds for 44 and the weights that get used the most are 245 Keith and the 300 Keith. The 300 actually finishes up ~320 with WW's and I can not imagine ever needing more than that. My goto loads are 19.0 gr 2400 for the 245, and 15.0 for the 300. Work these up and don't start there.
