I have a Ruger takedown 10/22 that I put a Vortex Venom 3moa sight on. After sighting in at 50 yds. I shot a 5 shot group of under a half inch. I was impressed with both the rifle and optic considering there was no magnification. Anyway, I took the rifle apart and put it back in its case. The next day I take it out and it shoot 12" low 5 o'clock. Re sight it and two days later it's 8" 11 o'clock. Two days later 4" left @9. So, is it the rifle or the optic?
