Congrats. Yes it will help but you are still setting expectations above what the ballistics say is realistically possible.
A prairie dog is about 3-3.5:" wide. One MOA at 1500yds is about 15.5". I've never heard of a 6mm in any caliber delivering that kind of cold bore accuracy at 1,500yds.
That doesn't make it completely impossible but it does make the expectation unrealistic even with a bench rest rifle under ideal conditions.
