I'm going to another 300 yard reduced match tomorrow. The first time around, my zeroes were totally screwed up. What I thought was good enough to whack a 12x12" steel plate off a bench at 200 yards was about 3 minutes too high in the offhand, I reckon. Work and other things hasn't left me time to get back out and work up a proper 200 yard zero, so I'm going into this one with my pants down.
My question is, knowing that all rifles and loads are laws themselves, is there a good rule of thumb for a "close enough to get on paper" 200 yard zero? When I left the match last time, my sights were pretty decently on for 300 yards, even though I was all over the place, but I'm gonna assume that was lousy position on my part. So, let's say my sights are somewhat on at 300, how much do I need to dial down for 200? I'm shooting a service rifle AR, BTW, a Rock River NM A2. And should all my adjusting be from the rear sight only? I haven't touched the front post since I got the upper.
