It will depend on what bullet you are shooting but a ball park starting point will be around 1.5" @ 100 yards.
With that rifle I would think it will be harder for you to find a load that doesn't shoot.
I have the same rifle and I have not found anything that won't shoot out of it.
It just depends on what your happy with. Is 1 MOA good, or does it have to be 1/4 MOA. I have not shot anything through it that goes more than 1" at 100 yards. And that included the cheap winchester stuff from walmart.
Just decide what bullet you want to shoot and enjoy.
