Merry Christmas and Happy New Year to all! I bought new steel Bulgarian 30 rd mags for my AK47. They can came cosmolined, so I degreased with Purple Power then rinsed with water 3 times. Broke down, cleaned and lubed. When I loaded my last mag my follower would get stuck at the bottom and all my rounds would shake and I could pour the rounds out. Disassembled, cleaned, inspected, lubed 3 times. No noticeable irregularities. Same problem again each time. Plastic followers. Any ideas?
