Got a sightron 8-32 and put on my 308 for ftr this year. Our range owner decided to close the range. We found some more land and won't have pits up and running for a while so we are going to have long range steel matches. Is the moa2 reticle accurate enough to range with and if so how do I go about doing it. Will be shooting out to 1000 on 19 inch targets.
