Unburned powder

tstr · May 31, 2000, 11:28 PM

I purchased some AA#7, which is supposed to be, according to the label, ideal for 10mm. However, when fired from my Glock 20, I get flakes of unburned powder around the magazine. I'm curious to know what you all think or suggest.

I've loaded 180 TMJ FP from the min to the max load recommendations. And I've tried both standard and magnum primers.

Very common, and not a problem. Almost NO smokeless powders fully burn when fired out of a handgun.
