I have had several, most do quite well with large amounts of rifle powders, better will "Ball" powder. My issue is with Bullseye and small loads. my favorite load is 2.7g of Bullseye in a 38 special with a 148g HBWC. The only load my S&W Model 52 will accept. I have yet to find a powder measure/thrower that will do this consistently. Still load those by hand.
