Other than the shakes, I’d say a misaligned scope is the biggest reason for hunters missing deer.(imo) At a bare minimum run at least two rounds on a target before taking a rifle to the stand. Doesn’t have to be a fancy target, just make sure you are zeroed in at what ever range you are shooting in. I’ve heard it too many times, I had it zeroed in last year. Why is it off? Can not answer that for anyone… in transit… the wife dropped it while cleaning around it… ??? I know most careful hunters return their rifle to a safe and it never gets touched, but still a good idea to check it. on another issue, remember to check it if changing bullets. I got an 1 1/2" drop going from a 150 to a 130 grain.
This is my .270 at 100 yards with 130 grain core locks. Glad I have a few rounds left, hard to find right now.
