I load for three 270 wby's, and never had a lot of good results with getting the 140's to shoot in mine. With 130's the first powder to try is 7828ssc, and with 150's try RL25 frist. I have pretty much settled on the 130's for 270 Wby, with a modern stout made 130 gr bullet @ 3500fps, I have no problem using them to take game including moose and elk at reasonable hunt distances.
