I get outstanding accuracy from my Savage Tactical 7STW with 78 gr IMR 7828 140 ballistic tip at about 3300 fps from a 24" barrel (wanted an STW and it wasn't factory chambered at that time in a lefty, rechambered 7mag). Consistently well under .5 moa.
I have yet to kill a deer with this load, but I shot a small coyote at 362 yds quartering towards right in the sternum and the bullet never exited. That kind of bothered me as to the potential performance on deer at that range. I tried RL22 and didn't quite get the tight groups. Haven't tried any other powders but 7828 seems like a perfect match for this round with 140-150 gr bullets.
