Composite Case Ammo... Thoughts?

Saw a box 308 TV at Bass Pro yesterday at $70, thank you but L No

Years ago I bought some polymer cased 5.56 ammo. It was lightweight, it fed into the chamber well and all went bang. The problem was the case head separation. Every other round would extract only the case head and leave the body stuck in the chamber.
Maybe these guys have solved that problem.

I have some of those cases. They work great when enlarging the primer pocket to accept a 209 shotgun primer with a .22 pellet pushed into the throat of the round. It will completely penetrate a 2X4.
Built several of the same rounds with solid brass cases that required a punch at the neck to stop the pellet from falling into the body of the brass. Brass cartridges expand and stay there. The poly cases went right back to original specs so the pellets could be easily retained.
Not my design, I copied it from some of the same items for sale on the internet.
Actually made a thread of that project and posted it on here 5 or 6 years ago.

If it works and the price could come down substantially, I wonder if I could replace the steel case ammunition market.
