Thread: Sighting in your hunting rifle

I usually do the X-inches high at 100m for X-metres zero method. Not a long range shooter, no rangefinder or fancy scope so it suits me. My 303 and 223 are sighted in for 180m and the 308 for 200. And usually that works out around the 2 or 3" high at 100 (about 1" high for the 223 & 1.5" for 200m zero).

But I also use the Nikon Spot On app to check zeroes. It's not a super duper flash ballistic calculator; but has most factory ammo (and you can put in custom load velocities etc) and is a good basic free app. It was very helpful when I first bought the 223 as tere was so much conflicting advice about zeroes. You can scroll through the (Nikon) scope models in the app to get something that matches what you have. All mine are basic Bushnell Elite 3-9's and a 2.5-10 on the 223, so pretty easy to find a similar scope. The app might not be everyone's cup of tea; but works well for me. Cheers
