    Howdy gents,

    Like most, I've been using Retumbo and H1000.

    Decided to pickup up some Magpro just for something different to try. Not finding a whole lot of testimonials via search function (I saw this one )

    I've heard some say they get good results and others say it's also rather temp sensitive.

    Happy to hear any and all results.

    AA says 93 grains is max with a 250 grain bullet @ 2925 fps. The 300 grain bullet used 91 grains for 2750 fps. All bullets were from Sierra. The burn rate is right between AA3100 and H450. Now I'm a big fan of 3100, but you can't buy it anymore. I think H450 would also warrant a test, and maybe N165
