Saw a number of new Savages on GB for about $250, so a feller could try one out pretty cheaply. That rifle doesn't appeal to me much, though. Ammo prices were kinda all over the place.
IF CZ made a 455, I'd probably buy one knowing I could switch it over if the round died off completely. I would definitely buy a 455 barrel if available from CZ, but likely never a $400 one from Shilen etc, unless I get REALLY bored.
