RE: 500 S&W???
My wife, she is the best, just got me a BFR in .500 for my birthday. Told the shopowner that she, about 5'4" and maybe 130, was, in fact going to shoot it herself.
I found the recoil to be quite mild, much more so than what I expected for something so big. QUite mild and comparable somewhat to some hot .44 loads I have made.
