My oldest son has the exact same rifle in the same caliber. Stock, his shot 1" @ 100 yards using 150 grain Sierra SBT and both IMR4350 or IMR4831. He has replaced the stock and converted it to accept a magazine and we just got done putting a Vari-X III, 3.5X10 on it. Our range is limited to 550 yards and we are able to hit clay pigeons at that distance using it. I'll bet that gun is going to be able to shoot a lot farther than you or I are comfortable with
