Yep, I have had a few. A brand new .22-250 bdl that the head spacing was so tight I could close the bolt on a chambered round. Remington no longer chambers that cartridge in the bdl line. A .300 win mag adl that shaved off the brass casing so bad that after four rounds it became difficult to chamber a round as the shavings worked their way into the chamber. A sps 7mm mag that had a bad chamber and could not extract the fired case without beating the bolt back. All of these rifles were bought new in the box as I don't buy used guns at all. I have one Remington at the moment, a 700 sps 7mm mag that replaced the one with the bad chamber. It works and shoots great.
