I had bought a dozen 30's from either Cheaper than Dirt or Sportsman's Guide
First mag ran flawlessly, second bang jam-rack shake same thing

Third mag ran them all
Now you all know what was going on but I was really straching my head being a Thompson newbie.
Anyone need a semi auto mag?

Hard to tell right off if round or a little bit oval ain't it??

At least I have a WH that will run without changing any parts right off the bat so at least that is something to be happy about.
