I had one of these baby monsters when they first came out. They really knock the crap out of feral hogs. The cool thing is you can buy plated bullets for reloading

But the most versatile bullets are the Rainier Ballistics offerings 275gr-400gr

I sold the gun because it dawned on me that a shotgun could do the same thing if not better with custom cast slugs for a hell of a lot less $$$.

But a .50 hole in a Ar15 barrel is something kinda neat.
