Your probably interested in rifle ammo but I have loaded the 44 mag 225g Hornady FTX/SST with great results. I also have some 265g 44 mag SST that I'm going to shoot out of my 50 cal ML using sabot sleeves. I prefer to shoot 44s & 45s with sleeves vs 50 cal out of the ML. I get better patterns. I think the longer bullets for the same weight shoot more accurately. Plus, your choice of bullets is greater.
