Model70Guy, I guess if you zero for (minute of deer) most folks would not notice temp and humidity variations. However when shooting at a 1" bulls eye at 300,it is noticeable.Took my 1000 yard rifle to the 600 yard range and noticed a change on the second day we shot with only a 30/40 degree change. Reloader 22 changes a lot more than Varget for me. Most of the time a 1 to 2 inch change of POI on the side of a deer won't make a lot of difference to the deer. I was not saying any ones gun was not zeroed to their satisfaction. I shoot a 160 Sierra game king in my 7mag, 7STW and the 7mm ultra when using them for hunting. I still like the old 264 mag for my area.What caliber F class rifle do you prefer ?
