Mine is the old 760 but almost the same thing. I've used several different loads and it doesn't seem too particular as far as accuracy is concerned. The bullet I like best is the Hornady 150 SST. I've used several different powders IMR4895, H4895, IMR4831, H4831, Win. 760, IMR7828, & IMR4320. All these powders have worked well for me but some will give more velocity. I've owned my 760 for over 40 years and it has served me well. I hope yours does the same.
