MRAD reticle yardage measuring: tips & experience

[need4sneed]

I’m looking to practice using my reticle to range deer while I can verify with a working rangefinder.

My thought is to keep a card (like dope) with:
“500/Mrad = yards” but also a listed chart of solved equations for yard increments 0-600.
Obviously a big part of this is to pattern in some memorization.

BUT, any considerations to: belly to back variations (specifically, does and young deer to mature bucks)
Is there a known range point where reticle accuracy is completely compromised (on a 14x or 18x zoom max)?
Any other tips or experience to speak to?

Yes I had a rangefinder go down on me and yes I am very salty about it. Looking to add a parachute ranging plan to my skill set.

The mil relation formula is below, you’ll need the average size of a deer say from top of back to belly then multiply that by the constant (27.77) then decide by mils. It works best when using a reticle that has the mils broken down to 1/10ths somewhere on the reticle and always estimate to two decimal places (ie: 1.25) for best accuracy. I posted a pic of the tremor 5 reticle as an example of the 1/10th section.

You could do the math prior to give you the mil sizes for a dope card.

Yards
size of target in inches * 27.77 / size of object in mils = range in yards
