These are true velocity’s new polymer case. They have a 3 of different calibers available. 12.7x108, 50bmg and 5.56mm Fucking rad, thanks! They are original designed for the DOD to help reduce munition weight on helicopters. My boyfriend and I were discussing using them boat hunting because of the weight reduction lol plus… floating casings? Yes please. It’s not all polymer. There is metal still in the case. Just in the areas that need it the most. You can see here. They are steel coated in poly. The ones in the op look smaller than the .50 but bigger than the 5.56. So what other caliber do they make? There was a .308win they made, I have yet to see any on the market yet. Pcpammo use to make the exact same way. There were some catastrophic issues with them. A bend or scratch in the poly could make a single round go Kaboom. I’ve reloaded some polymer cases. They are the bee’s knees. -- source link
