The key phrase is “in the future”. It’s not a new idea, in the ‘80’s plastic cased ammunition actually made it to a gun store near me. It required a special healed bullet to “snap” into the case to help with neck tension issues and could be reloaded with a simple hand tool. It flopped.

Around 2010 a friend showed up with some ammunition that was going to be the next big thing once it passed military testing, a hybrid brass/plastic case. He gave me the better part of 1000 rounds because, using standard bullets, it lacked sufficient neck tension to function and stay together in AR rifles and he knew I had single shot .223’s. It wasn’t even worth shooting in them and I gave them to another friend myself, only keeping a few examples.

In some rifles they would plink along OK, some they would run OK but if one attempted to unload the bullet would be pulled from the case, staying in the bore and dumping powder in the action. Others had chambers that were not smooth enough and would shred the cases upon extraction.

Someday I think they will get there but I haven’t seen sufficient evidence that goal has been reached yet.
I think I still have some polymer .38s in the basement somewhere.
