Here is what I found on this very web site.
I’d guess that 90% of the 200+ scopes on the line at the 2012 Nationals were Nightforce 12-42s with 1/8 MOA clicks. The eighth min clicks are invaluable for getting your elevation tuned in the 10 ring. If your shots are grouping slightly high and you have ¼ min clicks one click and you are now grouping slightly low. You are shooting at a known target at a known distance with rings that correspond to MOA (IPHY) measurements, you need all the magnification you can afford with a reticle that you like, that is thin enough not to cover too much of the ½ MOA X-ring at max magnification. You do not need (or want) a FFP reticle, they are too thick at high mag, they increase cost and they serve no purpose on a defined target at a known distance. If you hit low and right in the 9 ring you can look at the target and see that you need to come up ¾ and left ½ and having turrets that will get you there is good. Mil turrets are going to make your life harder, and you don’t need a reticle measure anything, the target is laid out so you should know the distances. That doesn’t mean you can’t come out and shoot with anything you’ve got, the guy shooting next to me yesterday was having a blast using a 10X SWFA. Nightforce 12-42, 8-32, or the new 55x competition scopes are all popular, for less money the Sightron SIII 10-50 or 10-60 are good scopes, some folks are running March high mag (50x, 60, or even 80x) scopes. All are SFP scopes.
If Mr. Holy Shit disagrees with the above sticky found on this site I would love to hear it.
