"We are going to show you some different ways to boresight a rifle when you have a scope on it. And we are going to show you everything from the original way years ago that we do in the field if you don't have any equipment with you all you have got is your rifle and some ammo. We will go on from that to show you so me different more modern ways that they have come up with to boresighting a rifle. If you happen to have them with you in the field you can do it. If not you can do it at home. It's equipment that you will have to buy, but the original way did not have any equipment just the rifle, the scope, and the ammunition. You start out in the field by removing the bolt from the rifle, set it aside, and you will need something like sandbags or devices to hold that rifle very steady. At about twenty-five yards distance you will set up if you have it you can set up a sighting target like this. You can see it has one inch squares, and very bright orange cross arrows in the center to put your scope across here is dead center on. If you don't have this pick any target that you can that you can set your cross arrows dead center on. You are going to set your rifle nice and firm and solid in whatever you have to hold it, and then visually look down the bore of the rifle out the front end, and put that sight picture you have directly on the target. Then very gently you have already taken the covers, caps off of your scope you will have a device on each face that allows you to move the cross arrows to that exact point that you have sighted through the bore. Twist those cross arrows, and move them until they are dead center on the target, put the caps back on again, put your bolt back in, and using those same solid rest that you have at twenty-five yards no more you will shoot a round or two into the target. If you are very good, and very steady you can shoot one round see where that is. Once you have fired that round in the target, let us assume for example that you have fired your round in the target after your sighting in, and it was only let's say one inch to the left on the target, and one inch high. You would adjust the scope to move the cross arrows over and up to that point. So that would be maybe four clicks over and four clicks up. Put the cross arrows back dead center on target, and squeeze off another shot. Being very careful to hold your cross arrows dead center on the target. If you are good, and you are careful, and you are a bit lucky you can get your boresight in one shot at twenty-five yards that stretches out to one hundred, and you are good at one hundred yards. The other ways to do is you can get a boresighting kit like this. This gives you what they call spuds. Different diameter units that fit down the bore of the gun, and lock in place, and then you have your scope aligner that clamps down to them. You sight through the scope, and there is a grid a across grid on here just the same as that grid that you see right here. You align your scope dead center, go back out to twenty-five yards in the field, then shoot it in. Everybody's cheek fits a little different on the rifle so you will need to sight it in even if you have a professional boresighter. A couple of different ways you can buy a laser boresighter. This fits down the center of the muzzle of your gun, turn that laser sight on, use these at twenty-five feet, cross arrows, line this red dot up, and bring your cross arrows in line with the red dot. One other modern way is you can buy the appropriate cartridge for your gun. Fit that in the breach, close the breach on it, that automatically turns on the red or green laser dot dead center. Adjust your scope cross arrows right to that dot, get out twenty-five yards, and have fun."
