I can't seem to find a load that works well in my GLOCK 21 using Hodgdon Universal powder. I've worked up good loads with it in 9mm, .40, and .38spl. I have found loads I really like in .45 with regular Clays powder, but the velocities are so low with that fast burning powder.... I tried the loads listed on the Hodgdon website using Universal, and they didn't eject well at all. Recoil seemed sluggish, even with the upper end loads. I checked my overall cartridge length, and increased the crimp a tiny bit (I can't crimp too hard because I'm using Berry's Plated 185gr) and it made no noticeable difference. I thought I had the problem solved when I checked the same load in my Speer reloading manual, and found that their loads for the same bullet weight and powder BEGAN with Hodgdon's TOP charge weight, and went WAY up past that. When I tried those recipes, the ejection problem went away near the top end loads, but now, it has a LOT of flash and is throwing unburnt powder like confetti out of the barrel. I've never had this much trouble finding a good load in 25 years of reloading. I've used unique in .45 occasionally, and don't remember having any trouble. universal and Unique have about the same burn rate, so I don't get it... Help !
