Ruger all weather 270wsm with a nikon prostaff 3x9x40 s/s synthetic stock. After shooting patterns with most of Winchesters factory offerings, i.e. 130 and 150 c/t bst's and 150 gr p/p's. Didn't try the failsafes or any Federal's loads so can't comment on them. Anyway like I said after shooting patterns, my first handloads of 130 gr b/t's and 140 gr sst's using the accuracy load noted in the nosler data of 59.0 gr of I4350 for the 130's and 58.5 for the 140's. Both loads 4 shot groups of 3 inside and inch with 1 flyer about 2 inches off which most likely is me not the load or gun. I'm quite happy after the way the ww factory ammo shot. Now it's time to tinker a little more.
