Ive got a video somewhere around here of a couple different members shooting a 50 Beowulf that was stuck on top of a FA lower.
Sucker was kinda mean...I can only imagine a BMG round through it lol

There's a plethora of wildcats for reloaders too. As a matter of fact there is a pretty cool upper for sale in the parts section riggt now.

Forgot 5.45. Alexander Arms has/had a .17 HMR. There is also a 5.7 AR.

That 45 raptor is sweet. Never heard it it.

277 Wolverine is not based on the 6.8 case, it's a 223/556 case necked up to 277.
