How to Zero a Hunting Rifle – A Step-by-Step Guide for Precision in the Field

Zeroing your hunting rifle is one of the most important steps to ensure ethical and accurate shots. A properly zeroed rifle aligns your point of aim with your point of impact, giving you confidence whether you’re stalking deer in the woods or preparing for a long-range shot. At Sportsmatch, we know that reliable scope mounts are essential for maintaining zero under recoil in tough field conditions. Here’s a practical guide to help you get it right.

Step 1: Preparation and Safety

Start with a stable shooting platform, such as a shooting bench or bipod, at a safe range. Ensure your rifle is unloaded and use high-quality ammunition consistent with your hunting load. Mount your scope securely using precision mounts like those from Sportsmatch UK – their lifetime guaranteed designs help prevent loss of zero. Bore sight your rifle first (visually or with a laser) to get on paper quickly and save ammunition.

Step 2: Choose Your Zero Distance

For most hunting rifles, a 100-yard zero is ideal, offering a flat trajectory for typical game ranges. Some hunters prefer a 200-yard zero. Check your ammunition’s ballistics data or use a ballistic app for best results.

Step 3: Fire Your Initial Group

Set up a clear target with a distinct aiming point at your chosen distance. From a stable position, fire a three- to five-shot group, taking time between shots to avoid barrel heat affecting accuracy. Focus on consistent trigger pull and breathing as slow as possible.

Step 4: Measure and Adjust

Examine the target. Measure the distance from the centre of your group to the bullseye in inches or centimetres. Use the scope’s adjustment turrets (usually ¼ MOA or 1/10 MIL clicks) to move the point of impact towards the point of aim. For example, if your group is 2 inches low and 3 inches right at 100 yards, adjust elevation up and windage left accordingly. Many modern scopes make this intuitive with clear markings.

Step 5: Confirm and Fine-Tune

Fire another group after adjustments. Repeat the process until your shots consistently hit the point of aim. Once zeroed, test at other distances to understand your bullet’s trajectory. Always re-check your zero before the hunting season, especially after travel or adjustment to the mounts.

Zeroing takes patience but pays dividends in the field. With Sportsmatch’s rock-solid scope mounts ensuring your optic stays true, you can focus on the hunt. Remember: practice makes perfect, and a well-zeroed rifle is a responsible hunter’s best tool.

Height of Scope Mount Required

In each product catergory we state a maximum (upto) objective lens diameter dimension. Due to both rifle and scope designs varying this can only be used as a guide. If you are unsure that the height of the Sportsmatch scope mount you have chosen will be sufficient to clear your rifle scopes objective lens from the barrel of your rifle, we suggest (prior to purchase) you check. The way you calculate the clearance is by halving the overall outside diameter of your rifle scopes objective lens and then deducting half the rifle scopes body tube diameter. For scopes with a 1″ inch diameter body tube diameter this would mean deducting 12.7mm, 15mm for scopes with a 30mm diameter body tube and 17mm for 34mm scopes. This dimension then gives the figure comparible with the ‘A’ dimension that is shown below. The amount our ‘A’ dimension is greater than the figure you have calculated is the amount of clearance your scopes objective lens will be clear of your rifles barrel (dont forget to allow around 2mm for the scope covers). Calculating your rifle scopes clearance in this way does assume your dovetail or Picatinny rail is not raised above or below your rifles barrel. Please consider that rifles with grooved receivers such as some models of airgun and .22 rimfire rifle will mean the scope sits lower than a rifle with a raised dovetail or Picatinny base fitted. Something else to consider is that some rifles with a high or adjustable cheek pieces may require high or extra scope mounts so that your eye is in line with the rifle scope and your head is kept in an upright comfortable position.
