SGT. I had the same question about my 15 MOA mount. Anyway you have now gotten sound advice from the other guys. One thing that was suggested to me is to get the book The Ultimate Sniper, they sell it at midwayusa.com. It is soooo full of useful info, i suggest to everyone now that shoots long guns to go ahead and pick a copy up. It is well worth the $30 something bucks and certianly worth the time to read. So far that has been the very best advice JD has ever given me(and he has given me a lot of advice).
