One shot zero

[offroader1006]

i know, but i had to take a swing at the horse.


i would never consider my rifle "zeroed" with one shot.

close, maybe. but zero assumes it is dead nuts where the grouping will center. no way one shot can ever determine that.

PR: I will admit this much. Is it possible..? Yes. Anything's possible, according to quantum physics. Is it statistically likely..? No.

You have your own way of doing it and your own opinions about it. I have mine. Perhaps we should just leave it at that.

I had trouble zeroing a rifle one day (brain freeze on my part to be sure). It turned out the scope mounts were loose - it was a Ruger 77 so it was completely my negligence.

If I'd have tried the one shot zero who knows what would have happened, but the rifle was not zeroed that day, but at least the several shots I fired convinced me something was wrong and that I needed to diagnose the problem.

Normally I shoot three shots before I even touch the scope. Sometimes I don't and it usually works ok if I'm using ammunition of known accuracy and the scope is already close to zero.

Occasionally that first group of 3 shots proves that the rifle isn't going to be zeroed until something is fixed. On those occasions it's best the group gets fired first and not last.

I always fire at least three rounds after the last time I touch the scope and until this happens the rifle is not zeroed IMHO.

OK, So you want to shoot a group instead of one shot. The process could still be the same.
0, Make sure all screws and bolts holding the gun together are tight
a, Make sure the scope mounts are tight and solid
1, Shoot three, five or even ten shots making sure each shot breaks evenly and clean (hopefully you have a group, if you do not*)
2, Make sure that the gun is held firmly, Lead sled or other good bench bags.
3, Look thru the scope and hold the crosshairs on the point of aim.
4, DO NOT MOVE THE GUN!
5, Adjust them scope knobs so that the crosshairs move to the center of the group.
6, Shoot to confirm zero.


* If you do not have a group, either you have a crappy rifle** or you are not a good shooter***.


** If you have a crappy rifle, I am sorry for your loss. Spend some money and get a decent one.


*** If you are not a good shooter, get a GOOD 22lr rifle and spend a lot of time practicing perfectly, take a class, find someone who will teach you. You must be teachable, this is your attitude.



Also this does not work as well with iron sights. But it could with very good eyesight.
