I would like to add 1 thing , I mounted scope to a solid bench and put a 100 yards and put a tall target from Snipers Hide , and I ran scope up and down 10 mils and then back to zero , I also went 10 mils left and right not off anything not even .1mil when it is L or R 10 mils , I then put at a tall rex target at 100M and did full range of sccope which is 25 mils elevation and a total of 10 mils left and right being 20 mils I dialed like full ranges and scope always returned to zero ,, I use it on pcp but when I shot my Rugar precision 6.5 creedmoor I shot out to 1400 yards with a firing solution and scope is spot on , great glass , I one day was hitting steal 1000 yd and was swapping from this to my Pm2 5x25 and my PM2 5x45 and it keeps up , and at 20x it accually has clear image then my Atacr and My 5x45 , schmidt bender , Only glass I likes a bit better was my tangent I sold , This is a great scope for dialing long range and knowing it is spot on , but while I use it and other tier ones for hunting they not real practible meaning they add alot of weight to guns and to carry long distances it gets heavy I am older and weight is a factor now for me but great glass they came out with a 10x I may sell a few optics and try that one I had a new razor3 1x10 and I did not like it nor did I like the primary arms looking for a good 1x10
