nah, its an sks mag. out of the 4 i have, only two function with any reliability. i switched back to the stock 10 rounder, as it's never malfunctioned.
yep! i loaded up 10 cases to test 'em, and i've got a good thousand to get primed and ready. work's been pretty busy, gearing up for the holidays, so in a couple of weeks, i should have little else to do.
