I was curios how much travel effected. One rifle 3/4 other 1.5. Probably me then.
I have not noticed any changes in my 308, anywhere between Mexico and on up into Canada. But there are 6 clicks difference in the 100 yard zero with my heavy barrel 223 from a very humid Summer in Arkansas (220 ft elevation) to Summer in the Texas panhandle (3700 ft elevation) and much lower humidity. An inch and a half doesn't sound like much but Prairie Dogs are not very big. The hardest thing is to remember to take those 6 clicks out once I get back home!
