I just zero my turrets reguarily on my Sightrons, and it has become habit to check when I shoot, or take it out of the bag.
I dont see it as problem now. Strange how you get used to what you once thought was a problem. The grub screw idea is a good one if done neatly though but I do find that the weather conditions brings on two or three clicks adjustment sometimes.
Mick you're a wuss ! fancy selling your real...favourite scope! You will need to buy another now as your collection will look bare without it! My wardrobe top is looking silly now as its 4 foot wide and three deep in scopes stacked up, not all Sightrons of course, as I have the collection or Burris and Tasco Tr scopes up there with them.
The Sightrons dont have the best depth of field but they are bloomin clean and easy on the eye with a fantastic ret.
Tricky to get used to, but a lovely scope.
