I load for several 270s. I use several different bullets but all are 130 grain. H4350 and h4831 are my favorite with h4350 being my favorite of the 2. The powder I would recommend in this situation tho that works very good is imr4064 and has noticeably less recoil. A killer lower recoil load would be IMR 4064(start at 47 gr and work up to 49 gr) and some hornady 130SSTs. Guaranteed to shoot and kill
I support 4064 use in the 270.. that is what my preference is.. I concede to giving up a 100 fps Max velocity, but what I pick up is lower recoil, and what I consider improved accuracy.. which may be just the lesser recoil... for that 100 fps Max velocity I give up, two clicks on the elevation knob and its been compensated for.... my two favorite bullets are the 140 grain ballistic tip and the 160 gr SMP Partition...
