I have a new 30rnd drum. At 1st, I thought it was g2g, as I had it loaded full 30 of CCI Mini-Magz, wound as tight as it would go, but only shot 10 at the time, with little issue. Next time I went to shoot the rest,{sat for a few days} it was nothing but problems.Are the pro-mag drums a bag of #### too, or do they work better?
