I bought my 338win mag for $600 from a guy at work 5yrs ago. Sold the scope that was on it for $150 and put a Leupold on it.
My other no1 was a tropical 458winmag I bought off GB for $500 all so about 5yrs ago. Traded it for a S&W 29-3 then traded it for a Colt Ltw Commander.
Deals are out there it depends a lot on calibers and wood grade.
