Bought a 500 mag and shot it a few times. Just not for me.
My brother bought one years ago. I shot it once, put on the table and said, nope. My brother sold it shortly after thatI bought one when they first came out. Unpleasant, kinda useless. Not my thing at all. Mine hurt to shoot. I don't know if it was because the only ammo I could get was hot stuff, or what. I shot one years later and it was as bad as I remembered. I spoke to a couple of people who shot mine way back when and had also shot others, and they agree with me.
I would like one in a lever action rifle, though. That would be worth having.
