First, you can only bore sight a bolt action because you have to remove the bolt and actually look down the barrel. Set up a target at 25 yards and put your rifle on a good solid rest, sand bags work well. Look down the barrel while you adjust your rifle and bags until the bull of the target looks exactly centered in the barrel. Without moving anything, look through your scope to see where the crosshairs are located on the target. Most likely they will be off the bull. If you have to make a left or right adjustment, and your mount is capable of making them (usually by loosening a mounting screw on one side of the base while tightening the opposite screw) do that first. Remember to keep peeking down the barrel while you do this to be sure the bull is still in the center. Make final adjustments by using the windage and elevation screws of the scope. When you do this, it will look like the bull is moving closer and closer to the center of the crosshairs. When everything is lined up, take a shot at twenty-five yards. If you've done everything right, you should hit the paper. Make any other adjustments that are necessary to hit the bull, then try shooting at a new target at 100 yards, and you should at least, be close to the bull.
It helps if you know how the minute of angle adjustments work on your scope. Some are quarter inch meaning that one "click" will move the impact of the bullet one quarter of an inch @ 100 yards. So, for example, if your bullet is 3 inches to the left at 100 yards, you would have to move 12 "clicks" to the "R" direction. Keep in mind that because your twenty-five yards target is four times closer than the one hundred yard target, you will have to quadruple your adjustments when you are shooting @ 25 yards. That is, if you are hitting 3 inches to your left @ twenty-five yards, you will have to move 48 "clicks" to the "R" direction to hit the bull. Hope this helps.
The .270 with 130 grain bullets will kill a deer-size animal out to 500 yards. In fact most calibers will kill the game for which they are intended at ranges much farther than most hunters can accurately shoot. Be sure to know what YOUR capabilities, and don't shoot at anything beyond that. If you count on luck to hit something that's way out there, you are not respecting the animal. And, if by chance you score (you most likely won't) YOU haven't accomplished a damn thing.
