Well you said any & all comments, so:
I mentioned on another thread about an old friend, now sadly passed on, who had a 30-40 Krag. He got it from his dad and I think it was his gramp's too. He inherited it not so much out of loving kindness but because his dad had backed over it with the pickup, then pulled forward to see what he hit!
The barrel was as crooked as a dog's hind leg, you could see it from a distance! Regardless, Steve learned how to shoot it as is, and from that time on got his deer every single year! One heck of a fine rifle it was. Nobody else on the planet could shoot the thing accurately except Steve, but it sure worked, even with a badly bent barrel.
