The TicTac is likely worth 700.00 without the scope, 500 rounds is likely 1/3 of the way through it's accurate life. The Rem could be 500.00-700.00 depending on condition. With 500 rounds it still has tons of life left and is the choice if upgrades are something your into. As for the scopes, we need way more info. Could be anywhere from 300.00 to 2000.00. I doubt the leupold is a mark 4 on the Tikka, but you never know.
