Mark 4 Internal MOA

Finally got my new Mark 4 out today to sight it in. Great scope btw.
Is it common for a scope to have more internal moa adj. than advertised? My Mark 4 claims to have 70 moa on the specs but when I tested it after sighting in, I had 64 up from a 100yd zero and 16 down from zero.

I wouldn't necesarily say it's common, but a number of folks on this forum have mentioned that there scopes have more moa than advertised. I guess they figure it's better to advertise low and come out higher than vice versa.

Re: Mark 4 Internal MOA

A 6.5x20x50 I have has 76 MOA worth of knob travel.

Although I've verified the drops with the rifle it's on out to 1000 yds, I haven't verified it's actually has that full adjustment at the range.

If I was planning on ranges that needed the last 5 MOA of the scopes adjustment, the paranoid one in me would want to make sure when the knob is moving, the elevation is changing as well....at least for the last few MOA/clicks.

Just cranked a 25x Mk4 72moa(rated) + 1moa under knob zero.
It must be a tolerance for knob machining/setting.

Re: Mark 4 Internal MOA

Like Auto said, the turret might turn without the reticle moving at the end of it's revolution. Check to make sure.
