When shooting from my bench. At 100 yds. i'm right on, at 200 i'm 1.5"right , at 300 i'm 6" right, and at400 i'm 20" right. This was with my 223. So i bedded the one base made sure the scope was level, check the crown for damage, Same thing. I tried 2 other rifles , same thing. Needed new glasses so i went and had my eyes checked , no change in vision. Heres the kicker . Today i'm leaving for S. Dak. P D hunting. Why is this all of a sudden happening. I'm thinking these so called golden years ain't so.
