Well, this post is going so many different directions, I don't know where to start.
Gunut. No, $1000 is not a ball park figure. A decent Charlin 12 will be worth more than that. The really beat up guns seem to sell for $750-$1000. I don't know of any type of gun I can give a "ball park" figure for without at least seeing it. Sorry.
Kolhoznik. "Birdshot" isn't the issue. The promotional loads you get at Wal Mart are typically designed to cycle dirty autoloading shotguns reliably, and are some of the very highest pressure loads you can buy. You need to do some research on low pressure ammunition. My own sliding breech guns get fed some high brass, here and there, but, they are much newer than that gun, and triple proofed. An entry grade Charlin likely isn't, and would be better used with lower pressure ammunition. Using an older double of any sort does require an awareness of, and thought applied, to exactly what ammunition you are going to feed it. All those marks on the flats of the barrels MEAN something, and were put there so the user knew what he had.
Fox. You are an idiot. Jesus never beheaded or harmed anybody, loved the sinner, if not the sin, and encouraged us all to believe we were all sinners, and not to judge, lest we be judged.
The topic was fair price on a Charlin. You, per usual, contributed nothing. The Parker people are a smart group, who expect meaningful contributions, which, is why you can't belong there.
It is a bit different, here. Enough said.
Best,
Ted
