Buy REM Sendaro or XCR TLR or go Custom in 300WM

[Nel24]

I want to know what to go with buy a Remington Sendaro SFII or XCR TLR or build a custom job?? I like the idea of a custom rifle because there wont be one just like it as well as it will be accurate, but I dont know if its cost justifyable!! This rifle will be a .300 Win Mag. I've done two years worth of research and still dont have the answer. ANY opinions and ideas would help THANKS.
