hey i was at a gun show this past weekend and saw some 223 ammo with a plastic case i was just wondering if anyone else had seen these and what the purpose is and if there is any advantages or disadvantages to these

OMG I have no clue. If you try any, put on safety glasses and tell us all about it.

I have a old guns and ammo magazine. 1990's they claimedit was lighter and reloadable. Which I find questionable on both counts. I think there is a good reason that they are not popular or still being made. they also made them in 9mm. Weird idea don't fix whats not broke.

thanks for the info i was just wondering because this was the first time i had seen or heard of them
