The 270 is an easy cartridge to load for, and for deer I like the 130 gr. Partition or the 140 gr. Accubond. For 130 gr. loads, 55 grs. of IMR 4350 has given excellant results in 6 different rifles. 60 grs. of H4831 would be the next load I would try. It should shoot with one of those loads. (Those are max loads, so back off a gr. or two starting out.) A friend of mine recently bought some RL17 and has been getting impressive velocity, so I may give it a try when I get time.
