Thread: Sighting a 223 for longer shots

I use the Nikon Spot On website and downloadable ballistic "app" to work out zeroes. Most cartridges and their factory loads are listed and you can also put in handload info. You have to pick from the Nikon range of scopes, but my scopes are bog standard 3-9x or 2.5-10x so I just substitute a similar Nikon model. You can also dial in the sighting in range and sighting in distance. I've found it great and really simple. Hope it helps. Cheers
