    You are barking up the wrong tree on this one. That powder is WAAAAAAAAAAY TOO SLOW to work in the .338 Win Mag, which does its best work with powders more appropriate to the 30-06.

    Unless you are loading for a .50 BMG or a smaller chambering that is HUGELY overbore, US869 isn't going to work. It is just about the slowest powder in existence:

    Burn Rate


    Your best bet is to sell it to a .50 cal shooter or try to trade it for a couple pounds of H4350, H4831, or RL-19.

    VV N160 is comparable to H4831, so it should work just fine. Reloading data can be found here:

    Yes, for 22-250! Not my choice for .338 Win Mag. H4831SC is my go to powder my .270 AI, .300 Win Mag and .338 Win Mag.

    By any chance do you own a reloading book? If not, it's an excellent investment.

    Us 869 good for 338 Lapua

    Suggest Reloader 19 for 225 grain or Reloader 17 in 338 Win Mag

    Reloader 22 for 250's or H4831

    285 made for Lapua not 338 Win Mag

    225 very good in 338 Win Mag
