[QUOTE="HighBoard, post: 1200624, member: 71724"] My expectations may be part of the problem... I have personally only chambered seven Rem700 rifles. They have all been at least sub .5 MOA with good velocity. I can get my expected accuracy but velocity is not where I think it should be. With 168VLD's, I have tried: RE22, I7828SSC, I4350 & H4831SC. Haven't cycled thru all powders I have, but expected better results with the few I tried. Accuracy load: 168 VLD's 55.0 H4831SC, [B]2592 FPS[/B], .296" @ 100yd, 3.415COAL Any hotter, accuracy goes south quick. Best velocity / accuracy (168VLD) 56.5 I7828SSC, 2802 FPS, .686" @ 100yd Tried multiple powder/primer/seating depth combos. I get very similar results with 162 AMAX, 160AB & 150 Partition. 150 SGK & 140 Pro-hunter did NOT shoot worth a flip. Did get some 140 VLD's in and was thinking about giving them a try. I would be thrilled with these results if it was a factory barrel, but do expect more from custom. It's a blue-printed M700, shillen match barrel, used a PTG 280AI piloted finish reamer, headspaced @ .0015". I do neck size the formed brass. Have never turned necks. The more I think about it, I should probably be happy with those results and move on. Maybe someone knows a better powder? [/QUOTE]
