Just went to a gun show in Oregon and I hate to say yes But in gun stores they in that ball park to.Try to get them down it probly will not work but mabe you can get a box of shells with it. A 336 isn't going to be any cheaper come hunting season.
I paid $225 plus tax for my 1983 CS in .35 Remington in great shape a few months ago at a local pawn shop, but I think that was pretty much a steal. I do a fair amount of business with those folks, and they're the FFL I use when I buy on-line. If he's asking $300 for it, I'd offer him less, say $250. The worst he can do is refuse at that price, but that's where I'd start the negotiation for the rifle. I think I'd definitely pay as much as $275 for it and might go for $300 if I really wanted it. I know I've gone on the high side to pay for rifles I really wanted. After all, it's only money, and, in this case, money can buy happiness.
