Back in the late 70’s the guys I hunted with would always get together to sight in our guns just before deer season.
This usually involved enough shooting to start a small war.
I have learned since then that you don’t need two boxes of ammo to sight in your gun.
Forget counting clicks – one shot is all it takes.
Grab a friend and a screw driver and you’re ready to roll.
Here is the essence of this process:
1. Your gun shoots the same place every time.
2. Take a shot, line up the crosshairs with the bullet hole and be done with it!
3. The key to it all is holding the rifle PERFECTLY STILL.
Having a gun sled is really helpful for this.
So, let’s discuss these steps in more detail.
It always helps to bore sight your rifle first.
(Skip this step if you have an autoloader).
A simple way to bore sight your rifle is to remove the bolt, secure the gun, and pick a small object 25-30 yards away.
Look through the barrel and center the object in the bore then slowly raise your head and peer through the scope.
Adjust your scope so that it’s centered on the same object as the barrel.
You are bore-sighted.
Now, for that critical one shot.
Set up your target at 25-30 yards and make sure there is a 1” dot at the center.
This is critical, many guys try to start off shooting at 100 yards or further. This makes it so much more difficult.
Once again – SECURE THE RIFLE!
Movement is your enemy.
Settle the cross hairs on the dot and make your best shot.
Without MOVING THE RIFLE peer through the scope.
If the cross hairs are not on the bullet hole then once again line up the cross hairs on the 1” dot.
WITHOUT MOVING THE RIFLE have a friend turn the scope adjustments until the cross hairs line up with the bullet hole.
You should actually see the cross hairs “march” across the interior of the scope.
If you LET THE RIFLE MOVE while it’s being adjusted your one shot will not work.
If you have held everything steady your rifle should be perfect and your gun is sighted in.
Now, if you want to check your group fire three rounds.
I normally check my group at 100 yards.
In open country I sight my .270 three inches high at 100 yard.
This means no holdover out to 300.
My bullet drops an additional 6” at 350.
Then it drops one foot every 50 yards thereafter.
If your gun is off repeat the one shot process but do it at 100 yards not 30.
I have done this dozens of times; once you get the hang of it you can do it quickly without wasting cartridges.
It’s also a great technique for checking you zero in the field.
If you drop your gun then pull the bolt, look down the barrel and center it up on something 25-30 yds. away.
Hold your gun steady, ease up and take a look through the scope.
The crosshair should be perfectly lined up with the same object as the barrel.
This is a great way to sight in without burning up a ton of ammo.
