I hunted with that Battue using iron sights for 3 years before I put the scope on it. The irons where really good. Put the fiber optic on the target and at 100 it hits near the top of the dot and at 200 near the bottom of the dot. I shot 1.25" 3 shot groups at 100 and 2.5" - 3" at 200. But I also hunted with my CZ 550 LUX and Safari for 10 years more then that and still only use iron sights when I take those rifle.
You must have GREAT GREAT EYE sight ! Good for you !
