MOA Turrets

kdvarmint · 06-03-2011, 10:00 PM

I got this new vortex crossfire and it has different turret marks than of my other scopes which are marked in 10 click increments to 60 1 full revolution.
New scope is supposed to be 1/8 clicks and it is marked in 8 click increments, it reads 2 4 6 8 10 12 14 16 and 0 (18) being 1 full revolution.
Seems like that would be 1/4 clicks? Anyhow, how do i use this to dial elevation if I have a 100 yrd 0 and my sierra ballistics chart reads at 200 yrds bullet path(inches) -2.8 and bullet path(1 MoA)-1.3 ?? The more I think about it, the more confused I make myself. And I've been awake for almost 24hrs, it don't help!! Suggestions?

This is easy. Go shoot and zero it at 100 yds. Then shoot it at 200 yds and see where it hits. Adjust towards the point of aim. Shoot and see where it hits. Once you get it hitting your point of aim at 200, write down the adjustments. This should tell you whats going on with the clicks per MOA etc.

I recommend you shoot at each 100 yd increment you can, to verify your drop data.

Good luck with it.

I did, have to wait till Monday to hear back. I was able to make a chart with it, took a little time. I think on the turret 8 clicks should read "1" not "2", as it says 1 click = 1/8 moa on the turret. We'll see.

i have 1 also and from what i gathere it like reading a scale ruler in 1/8th" scale every 8 clicks +1 moa so if you have to go up 1/2 an moa then go up 4 clicks what you need to do is figure out what 2.8 "= how many moa and go up that many i use a ballistic calc on my phone that is set up for rifle makes it alot easier .
