[QUOTE="Coach Hunt, post: 523144, member: 18430"] Howdy Scout1 and thank you for your service. In my 7WSM I shoot H4831 and H4350 with a variety of 140 grain bullets. I tried RL17 and had the following results... THAT DOES NOT MEAN THAT I RECOMMEND YOU TRY THESE LOADS. They just happened to be safe in my rifle, 22"bbl Win. mod. 70. Nov. '09 50.6 degrees F Sierra 140 gr. GameKing #1905 Reloader 17 62 3103 fps ES 23 poor grouping 62.5 3131 fps ES 22 1 1/4 group @ 200 yards 63 3111 fps ES 12 1 1/2 group @ 200 63.5 3173 fps ES 2 1.08 group @ 200 two in one hole, three others horizontal, wind I guess 64 3222 fps ES 37 1 " group @ 200 64.5 3240 fps ES 26 3/4 group @200 April '10 97.7 degrees F same bullet and powder Temperature test 63 3207 fps ES 7 0.35" group @200 63.5 3243 fps ES 37 1" group @200 64 3281 fps ES 44 1.5" group @200 in the three loads I shot in both tests, for an increase of 48 degrees, velocity went up: 94 fps, 70 fps, and 59 fps while ES went fron 12 to 7, 2 to 37, and 37 to 44.
