    NO PROBLEMS at all Have used Ramshot and Tight Group and was not impressed
    Rated a 3 cause don’t belive in 10’s or top score and have only used 2-4 lbs
    please notife when back in stock

    Versatile and clean I have loaded 380, 9MM, 40 and 45ACP with no issues and great results. Bought it because PV only had #8 can of this pistol powder in the entire place so I had to try it or have no powder at all.
    Now I look for it and jumped on some today when it briefly popped up then poof sold out again
