Adjusting Ballistic Program For True Sightron Scope Click Value

I'm using Bullet Flight and the scope is a Sightron SIII 6-24X50 .25 MOA adjustments.

Now I marked 48 in on a board and centered my reticule on the top mark which was a 3" sticky target 100 yards away and began spinning the turrets up until my reticule centered on the bottom target 48" down. I then spun the turret back down to make sure it centered back up on the top target, then repeated this 3 times to make sure I had repeatable results.

It took 44MOA or 176 clicks to scan the 48". So 48/176=.2727" per click.

Although it tracks well, .25 MOA is .2617"

The way BF has Click value pre set in the options is one click is .250 MOA
To calibrate for my scope I would enter .260 MOA for one click right?

Is .2727" per click .260MOA per click. I had a simple calculation earlier that is where I got the .260MOA but I cant remember now how i came up with that value so I cant check it?

I guess what I'm asking is .260 what I need to enter in the click value box to calibrate my program?

Also while I was doing my test I forgot to check my windage turret to see what the actual click value was. For now I'm going to assume it is the same as my elevation turret until I get back out there and actually test it. Does anyone know if this is a good assumption?

Also if anyone else has tested to see what their actual click value was for thier SIII's feel free to share it.

Yes, .2727" is equal to .2605 MOA. So you would enter .26 MOA per click in your ballistic calculator.

Thanks for the conformation, I can breath now!

Can you tell me how you got that, I know its simple but I can't
do it again for some reason.

Well I thought I could breathe, I put .260 as my click value
and it did not change anything at all. My elevation come up
for 1760 yards with my EDGE didn't even change.

Elevation as .250 & .260 was 60.1 MOA or 1107.5"

Not sure why your drop calculation didn't change. By changing from .25 Moa clicks to .26 Moa clicks, the come-up should have changed from 60.1 Moa to 57.8 moa.

Re: Adjusting Ballistic Program For True Sightron Scope Click Value

For the first conversion from inches to moa, you need to find the ratio of inches to moa. 1 moa = 1.047". So, 1 moa divided by 1.047" gives you a percentage of 95.51% (.9551). Now you can use this value to convert inches to moa. So in your situation, your click value in inches was .2727. So, take .2727" x .9551 = .2605 moa.

For the second calculation, you find the ratio again. .25 moa/.26 moa = .9615. Your ballistic calculator showed a come-up of 60.1 moa for a .25 moa click value. So with a .26 moa click value, you would take 60.1 moa x .9615 = 57.79 moa. Hope that's clear as mud!

Thanks for showing me the conversion, that's sure not how I did it ,but
now I know how.

Ive been playing around and changed the click value to .3 then to 1.0 and
still no change at a mile. At first I thought it was something I was doing but
I'm starting to wonder if its the program.
