Polycase ammo
« on: March 25, 2018, 09:16:59 PM »
Polycase copper infused ammo, mostly polymer with flecks of copper has a bhn of 9.5. Any reason the cannot be shot from an air rifle barrel?

I can't speak for everyone, but I tried to shoot a few in my Freedom 9 mm. They shoot so-so. I suspect they'd kill better, but into clay blocks they tumble instead of ungluing or splintering.

Adding a bit...

I have two different brands of 9 mm Parabellum ammo which use frangible copper bullets. Both come almost completely unglued when shot into clay. But then again, they're traveling about 1,300 FPS, rather than about 750 out of the airgun.

I have an Omega compressor. If you're a fellow Guild member, and you pass through Roswell, NM, I'll fill your portable tank as a courtesy.

No idea.... Copper is softer than the steel of a barrel, as is the polymer, so the bullet itself should not cause wear.... Like with lead bullets, imbedded grit is the enemy for barrel wear, as the grit imbeds in the softer material, and then abrades away the harder one....

Thank you Bob and Alan for your responses. My first concern was the copper flecks against the steel. I may order 2 different weights and try them at 50 yards. There is an 80 something grain 357, should push those in the neighborhood of 950. I think their flame to fame is both the polymer and the shock value of the nose design, so it may not be fast enough to make them viable at my speeds. However if they are great penetrators, I’ll have a place for them.

While we're on copper pellets... I'm still wondering what became of the UMAREX Halox pellets. Last September or so, UMAREX didn't spare any expense advertising them. Apparently, they were (are) vaporware.
