I owned a Freedom Arms Model 83 in .500 Wyoming Express. It was a real beaut; and for sure the recoil got your attention!

I killed a doe antelope and also a muley buck with it; I finally sold it to one of my hunters so I could get some cash flow to have Rod build me my .475 Linebaugh custom.

But alas! This gun breaks the One K limit by two times!
