What Happened to the .50-.375? It was supposed to fire a bronze solid at somewhere near the 5000 fps mark. A barrel burner to be sure, but what ever became of it?
I think you're referring to the SLAP (Sabot Light Armor Penetrator) round, correct? I think it's a .355 not .375 that's available. They're not as easy to find as ball, AP or Tracer but are available, most likely from 50 BMG speciality vendors.
Uh...well...no. Even at .375 they were reaching a point of diminishing returns. I'm not suggesting there was a real good purpose for the beast, but it was interesting.
Hilarious! Actually, some gun rag person actually expirimented with a .30-.50. Fast, but ultimately useless, as it was inaccurate, over-bore, weighed 50 lbs....
I think the only company that made the rifle was State Arms, not much interest as it was costly all the way around. I'm sure Skip Talbot experimented with it before he passed.
I think going up in caliber on the .50 BMG case is a better design, something like the 14.5mm JDJ. Again you run into price, if you can wildcat the case yourself that's one less thing but buying the rifle is going to be a major cost.
