Hi I have 2 cz 452 one for day one with nv setup on, daytime one zeroed in at 75 yards for daytime shooting and the other at 50 yards for night time , take bunnies up 150 yards daytime but after 100 yards the holdover gets considerable so have to be spot on for head shots you have to know your scope and watch the wind, I use win subs and can knock of 5 or 6 before the others know what is going on , head shots only, body shots often pass through even at distance and boy the can ricochet
