Siteing in a rifle is one of those things if you don’t know then dang it you just don’t know. You know the dangerous end is the one that goes boom and you know enough to stay away from it. Great the rest is relatively easy. First lets provide the reason you want to site in your rifle. To accurately hit what you are aiming at! Sounds simple I know but it isnt a shotgun and no matter how many times you’ve see it performed in the movies you cannot fire a rifle from the hip and expect to hit your target. Let me digress in the days of old the siteing of a rifle was simple you looked down the barrel and fired. then fixed site placement came along and you looked down the barrel and fired then adjusted your sites and fired again until you could shoot the hairs off a gnats backside. todays methods are the same but with the cost of ammo you really should want to take advantage of the tecjnologies available today to keep the cost of shooting down. so ;ets go through some and see where we end up.
Think it’s too hard to sight in your own rifle? Not so! Here’s an easy way to do it yourself – and it’s quick and practically foolproof. (If you’ve already sighted in your rifle and just want to check your gun’s zero, skip to the section labeled “Shooting a group.”)
Bore sighting aligns the scope to the barrel and reduces the number of required shots to zero your scope. You can do this with a gridded bore-sighting tool you insert in the muzzle of your gun or by shooting a few shots that will serve the same purpose. The second method can only be done with a bolt-action, AR-15 or other gun where you can look down the bore of the rifle. And, you’ll need a range of 25 yards. First, secure the gun in a cradle and remove the gun’s bolt so you can see the bore. Line up your barrel on a spot 25 yards away. Then, adjust your scope so it’s sighted in on that same spot. Make sure the rifle doesn’t move and be sure to recheck the alignment.
Shooting a group should start at 25 yards. Pick a steady bench and use sandbags to support your rifle. Looking through your scope, aim at the center of a target and shoot three shots at one spot on the target. Measure the distance from where you thought you were shooting (point of aim) to the center of the group of shots (point of impact). Adjust your scope so the point of aim is moved to the center of the group. Shoot three more shots, and you should find that your point of impact is very close to your point of aim. To sight in for 100 yards, shoot three shots at 100 yards and repeat the procedure you did for shooting at 25 yards. If you usually shoot at distances greater than 100 yards (such as deer hunting), then you’ll want your point of impact to be 1-1/2″ to 2″ high at 100 yards. This allows enough bullet drop when shooting at 200 yards.
