Live auctions can be nuts. The excitement of that caller combines with egos to push some bidders well over the common sense line. $800 dollar guns selling for 2K is the result.
If you really want to see some buyers remorse go to a dinner auction with a pre-dinner cocktail hour. A buddy of mine, in concert with Jack Daniels and Adolf Coors, ended up in a bidding war over a very nice looking but proprietary Lazzeroni 8.59 Titan rifle. He walked away with it when it pushed North of $4,200 (45? Somewhere waaay up there.) He was proud as a peacock the rest of the night.
The next day he realizes that buying ammo for that mule-kicking blaster would be almost impossible, plus there were limited opportunities to actually need to use it, but he was stuck with it.
He later tried to trade me straight up from my CMP Rack-grade M1 Garand, I said no thanks.
So yeah, auctions are not often the sources of gun bargains anymore.
Stay safe.
