Rifle Scopes Zeroing a ZCO527 for ELR use

This is just a discussion mate no need to ruffle your feathers. The 55 MOA rail is already there and the rifle needs a further 10 MOA to hit the point of aim at 100M that means 65MOA lost. If it was possible to bottom out the zero stop lever under the turret but this is factory set at around 50% of elevation and so is lost to zero at 100m the rifle should be shooting high with a 55MOA rail and 10 MOA on the turrets but it's not !. This is possible in a NF scope hence my question. A 100-yard zero is not normal for ELR because elevation being is wasted as you rarely shoot under 800 m so zero offset is dialled into your ballistic app which takes this into consideration in calculating your dope.
That's funny ..... my 527 zco had 31.5 mils of travel after zeroing at 100 so roughly 108 moa. Using a 50 moa mount...
I never shot ko2m so.....

That’s not an additional 10 moa it’s a negative 10 moa. You need to think it through I think.
Or maybe my explanation is bad. That’s very possible.
The 10 moa you’re dialing to get a 100 yard zero should be compensated for by a 20 moa Mount. Something like the Spuhr 6002 or the ones ZCO sells which is what I’m using.

Yeah I've got 29 mils with 20moa rail + 20moa mount= 40moa total. I happened to stop by the house so I dialed mine all the way to see and it's 29 mil total that I can dial on my 527, which is what, roughly 97moa?
the more OP posts the more I think we're getting trolled by some airsoft n00b in his parent's basement. this can't be 2 pages of real fucking 'i can't do math or understand basics of a scope and cant but i shoot KO2M'
Chris its 55MOA on the rail and an additional 10moa on the turret so its 65MOA what am I missing?
you can't be fucking serious. he 'lost' 12-13mil because he ONLY has 20moa of cant. if he had another 40moa (12mil) of cant he'd be using all available travel...around 30ish
cant in a rail/mount doesn't LOSE elevation it fucking adds to it from optical center
take your 55moa rail and put a 0moa rail on. i bet you have about 52 moa of travel when zero'd at 100m

everything. you're missing everything.
zero that 10moa into the turret and have 107moa or travel left, or add 5-10moa of cant into rail/mount and have 112-117moa to use.
Ummm I dunno maybe perhaps how to zero a scope and possibly how to set said scopes zero stop correctly... Possibly missing how to do the math to estimate travel....
But I never shoot ko2m so....
I'm sure you podium regularly at the ol'ko2m
He dialled 12/13 mils to zero at 100 when he adjusted his zero stop he turned back leaving the 12/13mils on the turret. Look at the video !
I think it’s because he’s not factoring the spin of the earth. Remember if you’re shooting east and you’re located at the equator, the planet is spinning eastwards at approx 1000mph so you have to aim 55 moa low to compensate for where the bullet will be according to the orbit. Then you have to factor the curve of the earth at 8in per square mile.
It’s just basic Newtonian stuff they teach at the Ko4M.
After watching the video… he is right! At 3:08 you can see 12/13 mils fall off the scope. Watch close. Poof gone.
Just mount the scope upside down and you’ll get it all back.
Bob, do you bench 275 lbs? Have 200 bow kills? Worked in concrete for 28 years?
I think the answer you seek is the Quigley Ford 5-20 Dual Focal Plane scope. 234 moa of travel. You can shoot "soccer ball groups" at KO2M. Thank me later.

Perhaps ZCO can weigh in….but IIRC mine came out of the box with 35mils Up Elevation.
But I still don’t understand how a 55moa base loses travel from the scope? This reminds me of Billy Maddison in the decathlon. “Everyone is now dumber from hearing your explanation…may god have mercy on your soul”.
