i will be a able to tell you in the next few weeks. I bought a box and sighted my trusty old marlin 30-30 in at 150 yards. this should put me about -1.5" at 200yards and -18" at 300yards. I say Again SHOULD put me there. If it holds out to 200 i will be impressed. I like my 30-30 and this just made a good cheap and powerfull rifle that much better.
