You need to know the claimed muzzle velocity and the height of the site used to determine the drops at range. If it's a factory loaded Remington core-lokt 200g they claim 2,775 fps at the muzzle. Most manufacturers use 1.5" for the sight height. Using those numbers we can work backwards towards a "guestimated B.C." of ~0.245
So, for that theoretical velocity and sight height you'd want to be +1.0" at 50 yards.

Doubtful you'll actually achieve 2,775 fps out of your rifle and so your drops will be different than what's claimed on the box. But 1.0" at 50 yards should at least get you in the ballpark.
