Quick Answer
Sighting in a .45-70 lever gun requires a precise approach, using a 100-yard zero as a starting point, and adjusting for wind and bullet drop at longer ranges. Use a chronograph to determine your rifle's muzzle velocity and choose a suitable sighting system. Regularly check and adjust your zero to ensure accuracy.
Choosing the Right Sights
When selecting sights for your .45-70 lever gun, consider a high-quality aperture sight with a large enough objective to clearly see the target at long ranges. A hooded front sight can help reduce glare and improve visibility in bright conditions. For a 100-yard zero, aim for a point of impact 2.5 inches high and 1 inch to the left of the point of aim.
Zeroing the Rifle
Start by firing a group of shots at 100 yards and measuring the average impact point. If necessary, adjust the rear sight to bring the impact point to the desired 2.5 inches high. Next, fire a group of shots at 200 yards and measure the impact point. Adjust the front sight to bring the impact point to the desired 1 inch to the left of the point of aim. Repeat this process at 300 yards, adjusting the sights as needed to maintain a consistent point of impact.
Aiming for Elk
When hunting elk at longer ranges, use a spotting scope or binoculars to accurately judge the distance to your target. Take into account wind deflection and bullet drop using a ballistic calculator or a chart specific to your rifle and ammunition. Aim carefully, using the corrected point of aim, and fire a controlled shot to ensure a clean and humane harvest.
