How many rounds are you loading in a Hex Mag 15/30? The reason im asking is, if i load 15 the gun jams. S&W SPORT 15.

I had to download mine by one round at first, then eventually they started running ok full across multiple rifles. They are really quite poor mags, I returned most of the ones I had.

30. No issues. Even after mags staying loaded for over 6 months.

Get rid of the Hex mags. They're not that great. Get P-Mags or Lancer mags.

Can't put 30 rounds in a 15/30 mag. This designation means it's a 30 round size, but blocked to 15 rounds. He probably lives in Colorado.
