Even though the rifle has set up without being fired and has a low round count, you need to shoot the rifle before making any offer. Chambers are bad about pitting and not ejecting spent cartridge. It is possible that if it was left unclean that it might have some corrosion. I have had 4 or 5 different ones over the years and 2 of them would not eject the cartridge. Since the 308 is the most available of the 3 calibers, I think the $450 is about right...or it is where I live.
