270 WSM 140 gr. SST's and Sierra's accuracy load. Shot 1" at 200 yds. Their
manual is my favorite as I have had great luck with those accuracy and hunting
loads at the bottom of the pages, in several different calibers.
Have tried the 130g in two 270 winchester rifles and can't get them to shoot at all (about 3" groups). If you lived close handy I would give you 1/2 a packet.
