Zeroed a swfa 5-20 in a 308 yesterday. Have it on a 20 moa base. Have 16 mils of elevation which is more than I will ever need and have 10 from the bottom. Issue is I had to use 4 mils of windage to zero. I know this is a lot but is it acceptable considering how much adjustment is in the scope. I know something is out of line whether it is the base or base screw holes. Should I leave It or fix the holes, base, etc?
