300 WIN, Mag primers, IMR-7828SSC and 190 Bergers?

As the title says, I'm looking for loads, expected velocity for this combo. I can't find the whole combo, has anyone tried this combo? I had a load with RL-22, but unfortunately could not find that, but could find 7828. Also, is 7828 a consistent powder? Any help would be appreciated.

I would like to hear anything on this topic as well.

Well, after much waiting, I finally got to try it. I'm shooting 74 grains and getting AMAZING accuracy. 1/4" which is about as good as I can shoot. the faster I pushed it the more my groups opened up. that is with 190 Bergers and an 11 twist Rock Creek barrel, so work up carefully. I'm getting better accuracy than I was with RL22, but haven't had a chance to Chrono it yet. I'm excited overall, as 7828 is definitely more available than RL22
