It doesn't say even on the IMR website. I'm just looking for a powder that meters better than unique. Specialy in 32 h&r mag with such small quanityof powder. Thanks.

According to Speer's #13 manual they're both single base flake powders.

ben i made a dipper out of a 22 mag casing. it hold app. 5 grains of unique. it is extremely consistent due to the small opening.

i also made a dipper out of a .32 hr casing and trimmed it down to what i needed.

Thanks Gentlemen, I guess I'll stick with unique. I'll try your dipper suggestion Scott.
