Re: sighting in scope
I would also start at 25 yards. I sighted my NF 8-32X56 NXS on 12X @ 25 yards only 2" low, Then moved out to 100 yards and continued at 20X. I didn't use anything higher because of mirage problems. The 30 caliber holes are clearly visable at 20X. If I was shooting 223 I would probably gone up to 22-25X depending on the mirage.
