[QUOTE="swampratt, post: 2966839, member: 15054"] New gun and different powders. I take it to 200 yards and do a ladder test in the velocity range that makes you happy. I usually start just a tick above the start load and with your deal I would step up in .4gr increments. Shoo t at 200 yards and see which loads were closest together.. then work in that range of powder charge playing with seating depth and type of primers to really hone in on the perfect load. I also found when searching for the perfect load I need to anneal my cases each time. I leave the chrony at home when working up a load.. it can be misleading. I have had loads that were withing 3 fps of each other and they shot like crap lucky to hit 8" at 200 yards.. then other loads that were 25 fps apart but shot under 1" at 200 yards. Give the gun what it wants. 100 yard shooting hows me nothing.. many of my good loads shoot 3/4" at 100 but hold that same 3/4" group at 200 also. Odd how things happen sometimes. [/QUOTE]
