Not In my future. I'd rather have aluminum cases.
I actually got 3 reloads on aluminum 9mm cases.
On the 3rd trip I had about 4 cases split at the top. So I throw the rest away.
I bought a box of Blazer aluminum, and I shot them up. As I was picking them up to toss I notice they were boxer primed. So that light came on, and curiosity of how long would aluminum cases last.
I just had to try. So I ran into the house loaded up the 50 cases, ran back outside shot them, repeated.
So figure 3 reloads before splitting with Blazer aluminum 9mm.
I wonder if 38 Special aluminum are boxer primed, and how long they would last with lower pressure loads?
Activ shotgun shells came out in 1970 -1990 -all plastic but was a short-lived idea. Activ hulls were produced by Activ Corporation of Kearneysville, WV in the 1970s through the late 1990s. The shells utilized a material they called "biaxial" which basically meant that the "grain" of the plastic allowed the hulls to stretch lengthwise, but not outward. Biaxial material allowed "off the press loading" without resizing.I suspect it is the future.
They claim an improvement.How are they compensating for the heat removed by the brass cases? I remember when the army looked at this in the past it was a problem for FA guns.
They insulate the chamber and keep the heat in the expanding gasses which is probably where the "optimized performance" comes from.How are they compensating for the heat removed by the brass cases? I remember when the army looked at this in the past it was a problem for FA guns.
Your idea is better than mine, but the first thing I thought was, "3D printer time!"Plastic cases in a military context makes a lot of sense.
For all of the doomsayers: if this became widespread, just how long do you think it would be before you could buy molds and injection equipment for making your own cases?
It would actually make reloading a lot easier to be able to just buy a bunch of plastic pellets, put them in the hopper, and crank out brand new cases whenever I wanted. Machining your own molds would also be relatively simple. Which would make brass shortage for unusual calibers a thing of the past.
We’ll see. Engineered thermoplastic’s are $7-15 a pound. Cartridge brass is much less expensive. Any cost savings would be in the processing but that is all highly automated anyway. Remember the Active shotgun shells and the Wanda cartridges? That’s what they said, too.
