I'm not quite sure yet. I had it down to my father's place in Kentucky a couple months ago. I initially zeroed it at 100yd while I was breaking in the barrel, however, I hadn't planned on keeping this. It's got a 20MOA base on it so I had to use a shit-ton of the elevation adjustment just to get it down that far.
Anyways, I took the stock off to send it out for a repaint, so the previous zero is probably null and void at this point. I'll probably just zero it at 100yd again to finish playing with it until winter hits. At which point, I'll probably strip it down again, maybe send out the action for some work, and probably bed everything while I'm at it.
Ideally, I bought the gun for 600+ yd shots. But, I'm just getting into distance shooting so that's probably a bit optimistic on my part, not to mention we're in mid-ohio with little room to shoot. I need to dig up (or make) some drop charts for the rounds I'm using so I can determine an ideal zero for it. What that # is, I'm not sure yet. Probably around 300yd.
