I like the 5th pic in your link with the recoil mark between the eyes.
As far as I know, the 50 is legal in Florida, only illegal in Kommiefornia.
I know of no fed law that prohibits them.
Smile. Yes, quite a variety of photo’s on that website.
Imagine a 20mm rifle?
The average guy thinks that the $5-10 per round is expensive. I’d hate to buy 20mm ammo (or even components).
I like big guns. But am not as big as the guy in the photo you referenced.
