that is almost the exact load I use in my 7mm rem mag. 66.5 gr of Rl22 with Win primers and 140 accubonds. It shoots incredible, the only thing is I have lost ALOT of velocity. Im shooting a Ruger M77 with a 24" barrel and can BARELY break 3100 fps. I know its because of the shorter barrel, and with the accuracy averaging about .75 who cares about losing 150 fps.
