The Zero Check Thread

[Beavis]

20 shot groups should be the minimum, hot barrels be buggered. I guess I'll keep being a dinosaur and consider 5 shot groups is all I need. I cannot recall ever having to shoot 10 shots while out hunting. Tell me again why we need to burn powder, primers and barrels because someone decided its now necessary to have 10 shot groups for a hunting rifle?

Pretty much because extensive testing has shown that you need to fire a minimum of 10 rounds, ideally 20 or better yet 30 to get a good sample size that represents the true dispersion pattern of a rifle/bullet/powder combination. Shooting larger sample sizes and ruling in "flyers" gives you much better data to zero your rifle.

Most people can get by with an imperfect zero etc because of the size of the target and the distances they are shooting things at.
