My TAC A1 in 6.5 Creedmoor can reach out to a mile plus. But not with the stock 0 MOA base. My scope has 32 mils of adjustment, (less than some, more than most) or really about 14,4 mils of usable adjustments gravity being what it is and all. That takes my rifle out to about 1200 yards. If I use all of my holdover maybe 1700 yards. Past that it's pure guessing..... So why doesn't Tikka put a 30 MOA rail on this gun from the factory?. Its not like they didn't charge me enough money.
