    Great Powder

    I've used Autocomp for years. I load 9 major and have very consistent results. Doesn't work well for light loads. but if you load at the upper limit of standard minor PF loads around the 136 PF area, (or major PF loads) it works great.

    Excellent to feed your auto 9mm, 40 and 45s.

    Worked up a great load for my 9mm...easy, accurate dispensing and clean burning!
