[QUOTE="Bud Meadows, post: 89434, member: 169"] A rule of thumb I was taught when I shot for the All-Army Rifle Team back in the early 1970's was one MOA change for every 15 degrees of temperature change. Thus, if you zeroed your rifle at 60 degrees and then later shot it in 15 degree weather, you'd be 3 MOA low. Of course, this was shooting Lake City Match ammo in Match Grade M-14's. I still shoot Lake City Match .308 ammo in my Ruger 77V, and find this rule of thumb is still pretty accurate. [/QUOTE]
