nralifer Report post Posted December 20, 2015 My favorite powder for the 270Win is by far Superformance. You can get over 3000 fps with 140 gr bullets from 22 in barrels and get sub inch groups. Works well in 330 Dakota, 300 WSM also. Excellent replacement for H4831. Will add 100-200 fps. Does not work in the 308 Win For the 308, Leverevolution works very well. Need to experiment since there is no published data, but this has become my favorite powder for this cartridge. I use WLRM primers since these give the most consistent MVs. Accurate 2520 and H414 also work well. H380 for 204 Ruger is excellent. Can fill case to capacity and have slight compression using 39gr Sierra BK bullet. Easy to get 1/2 inch groups with this powder. Share this post Link to post Share on other sites
