Guys, i never in my wildest dreams knew what you guys have gone through with load dev. I know now!! The best powder ive found so far is h4350. I am getting 1moa accuracy at 100 yds w/o a sled at 3,600 fps with slight pressure showing. That cci 250 took the pressure curve out of the h100v with that light bullet. I lost a touch of velocity out of the 100v with them but 3,650 is nice! 100 gr nbt 58 gr h4350 is 3,578 avg. 59 gr 100v is 3625 avg with cci 200 is nice too, but primers show look out!
