5. Using a spotting scope if you have one, find out how far out you are from zero. Otherwise, walk up to your target and use your target divisions to get a measurement of how many inches up or down for example your bullet is off the target. Then adjust your windage and elevation settings up or down, left or right as necessary. Each interval (or click) on the adjustment turrets of your telescopic sights will move the point of impact a certain distance. You’ll need to check your manufacturer’s instructions to work this out. Remember that at 25 yards, an adjustment will require four times as many clicks than at 100 yards, e.g. if the adjustment is four clicks for an inch at 100 yards, it will be sixteen clicks for an inch of movement at 25 yards.
Don’t attempt to zero your rifle if the weather is extreme. Do it on a dry day with no wind if you can.
Don’t let your fingers get in the way of the rifle barrel or moderator or it can affect your zero
Not everyone can get their shots in a group, but this is important. So do fire five shots in quick succession. Don’t zero after a single shot or you will be chasing your zero for ages.
Remember, you’ll always have to fine tune your rifle to make sure it’s zeroed exactly – and it’s actually only the sight that can be adjusted, not the rifle itself.
