Can anyone help me zero and calibrate


Recommended Posts


Hi Danny and welcome.

Okay, I would assume you have never zeroed a scope before? 

Right. It's pretty easy really. Take the screwcaps off your scopes turret controls. These turrets themselves have turnable switch-buttons that alter your scope's reticle or crosshairs left  or right, and "up and down". Pay attention to the arrow indicator marks and which way they indicate up and down on the vertical turret and left to right on the horizontal turret.  Get to familiarize yourself with these turret controls. They work in a commonsense fashion. 

1. Measure out a set range distance of 25 yards or 25 metres. 

2. Set a target up. A clean unmarked MDF board and tape a card target to it. Your target can be a printed card from the shop or draw a circle and put a dot in the centre. That is your aiming point . As long as you have a solid backstop or clear space that won't have someone pop up behind it in  your line of fire. Now take the turret caps off your scope. The vertical turret adjusts vertical elevation or, simply "up and down". The turret to right horizontal is the Windage turret. This adjusts your reticle cross hairs to left or right of the centre of your target.

3  Fire five pellets and see where they group on the board or target. If they are high above your aim point and off to left, you need to lower the reticle by turning the elevation turret following the indication arrow down by 5 clicks. Usually this is to right clockwise. Keep turning this down 5 clicks and fire 3 or 5 pellets until your reticle is putting your shots on the level with the aim point to right (or left, however the case may be).

4. Now you need to bring the scope reticle to  left. Turn the windage turret control by moving the control by the direction arrows usually, to clockwise right. Turning the control right moves the reticle left onto your pellet group. Turning the control to anticlockwise  left moves the reticle to right.

Fire 5 shots to check where your shots are hitting on the target board and keep turning the windage turrets until you can clearly see how your point of impact alters nearer towards the bullseye or aim point, until you are hitting the point of aim mark on your target. 

When your shots hit the target dead centre, your scope is zeroed to a precise 25 yards range distance. 

To calibrate. Once your scope is in zero to your rifle barrel, set up targets at 5 metres interval distances nearer and further than your 25 metre zero range. Aim and shoot directly with your crosshairs on each target centre. You will soon see by how much your shots rise above your target as you shoot nearer to yourposition ; and fall below as you shoot further distances from your position. 

This will greatly help you decide how much holdover and hold under you will need to aim, to shoot accurately at your target at alternating distances.

Hope this helps. All the best.

Simon.

As above.... nailed it!!!

Only one thing to add.

When shoting you 5m or 5 yard ranges use a drawing pin as aim point then 5 shots at aim point on dp, 

Then move your cross hairs onto the group and make a note off how many mildots between group and aim point.

Ie... 30m zero

       35m   +0.5 md (hold over)

        20m  -0.5 md (hold under)

i make little range cards that go on my covers...

Keep magnifaction the same x8 x10

Unless its a ffp scope

As above.

There are some videos on youtube that are very confusing because they explain zeroing a gun with the weapon in a fixed and clamped position, which means you do the opposite to what Piano man has directed by first firing a shot at a paper target and then shifting the reticle onto the point of impact. To do this, the scope has to be aligned absolutely perfectly and the gun kept perfectly still.

With normal 'free hand' zeroing, its best to think of the turrets as controls for the point of impact and using them to 'steer' the pellet onto the mark on the target, the point of aim.

When setting zero, it is really important to have the rifle very still or each time you shoot, it will vary the shot position, so with this in mind, I would strongly suggest you shoot from a bench / table or laid prone on the ground. It will be a huge benefit if you can rest the rifle on a support which can be bought from any gunshop or use the leg out of an old pair of denims tying a knot at one end, fill about 6'' of the leg with rice or bird seed or something similar. Once enough is in the leg, tie it off using a tie strap. You now have a very stable shooting rest to help keep the rifle nice and steady while setting up zero.

Don't forget, rifles like different pellets so you will need to test a few to see what pellet your rifle likes. A good starting point would be in my opinion, Air Arms Diablo Field and take it from there. If you struggle to produce a tight group of pellet holes, try a different pellet.

You also need to keep a check on the air in your gun, I am not sure how many shots you will get from a fill of air before the power starts to drop off and your pellet group will slowly break up so a point to watch.

Enjoy your new gun Daniel.
