If there was no wind, I'd adjust a half minute to the left, then confirm the zero with groups at 200 and 300 yards, or out as far as you intend to shoot in the field. Don't assume that a 200 yard zero will give your 130 a 6" drop at 300, it might not. If you intend to shoot out to 300 or more, shoot at those ranges to make sure you know what happens out there, rather than depending on a computer generated prediction of your bullet's path. You might find for example that at longish ranges, your point of impact has moved left or right of center. Make a note of the drop and drift at ranges beyond your zero range, and make up a range card you can refer to for the correct hold-off at any given range. If you intend to shoot much beyond 100 yards, make up a range card for each different load you use.
Beyond that, don't be too concerned with shooting groups with your hunting rifle, other than to confirm your zero from time to time. Its the first shot out of the barrel that's the most critical one. Besides, its much more interesting to set out game sized targets at nonspecific ranges and try to hit them with the first shot from field positions, under various wind and light conditions in the field, than it is to shoot 100 yard groups from the bench across a manicured lawn. And if you don't get out and shoot in crappy weather, you won't know how to shoot in crappy weather come hunting season. In the meantime, spend as much time with the rifle as possible.
Conduct dry firing drills while at home. When dry firing, try breaking the shot without moving a coin balanced on top of the barrel at the muzzle. Start with a quarter, then try to reduce the time it takes to break the shot. When you can break the shot quickly without disturbing the quarter, try a dime. Trigger control lies at the heart of good marksmanship. Practice cycling the bolt at your shoulder and reacquiring the target as quickly as possible after you've broken the shot, without neglecting your follow through.
When you find that target shooting is becoming less interesting, try physically stressing yourself, prior to making a shot. A short run, for example, will produce a similar physiological effect to arduous hunting conditions combined with the excitement of taking a shot on a live target. Don't restrict your practice to any one position. We're inclined to shoot only from prone because we tend to shoot best from prone, but when hunting you might have neither the time nor the conditions in which prone can be used. Often vegetation or terrain will block your view of the game when you are attempting a prone shot. So sitting, kneeling, and off hand are more frequently the viable positions in the field, and one needs to be aware of how and when to use natural rests should they be available. Of course if you are provided with a shot that can be taken from prone, you should act quickly to exploit its advantage, and consider it a gift from the gods.
