Hey guys, I recently developed a load for my 7 mag using H 1000 and 168 bergers the only info on h1000 other than reloaders nest was on the hodgdon web site. The test barrel used by hodgdon was 24 inch and was using 69grains to 71 grains producing 2744 fps to 2806 fps. I have a shilen varmint contour 27.5 inch barrel so it wasnt apples to apples. I started low in a ladder test from 63 grains increased by half grain till I reached 66.5 till my groups started getting wide. My sweet spot of 66 grains produced one hole groups as long as I do my part. I chronographed it with 66 grains and I was pleasantly surprised with a muzzle velocity average of 3050 fps. My question is is this odd for that length of barrel to peak at 66grains where a 24inch is using 69 to 71 grains?
