Rifle Scopes Bullet drop and turrets..

[wjwill]

quik question..... My scope turrets are 1/4 MOA adjustments. I have the scope zero'd at 100 yards, at 200 yards, I am dialing 2moa(8 clicks) on the scope for a direct hit. I even did a hold over on the rest and the hold over is at the first hash mark right below the center of the cross hairs. Picture of reticle included.


The scope is a US Optics ST-10 with erek knob(1/4 moa) and it has a JNG MOA retical.

Giving that information, would you say I my bullet drop at 200 yards is 4 inches?

Sounds like it to me, but I'm relative new to this. Let's let the experts chime in.

Yes, give or take 0.1" because 1/4 MOA is not EXACTLY 0.25" @ 100 yards.. You're thinking correctly.

This article has info on MOA:

Minute Of Angle

My advice would be to stop thinking in inches, clicks or worrying about bullet drop. And just dial your dope. Get out to the range and confirm what you are supposed to dial to get your bullet out of your rifle to varying ranges. And right it down.

MOA is NOT inches, it is a angular unit of measure.

You got it right. As billyburl mentioned, don't think in clicks or worry about counting them, think in MOA. There are many good ballistic programs that will allow you to punch in your load data and have a drop chart solution for multiple ranges.

Thank yall for the help... I am going to hit the range again and keep giving it a go.

what billy said.

if you can PM me the ammo your using, bullet manufacture / type and GRN weight, see if the box has a muzzle feet per second FPS on the side, & scope sight height (measure in inches from firing pin to the middle of your scope), then I'll get you a balsitics chart. Takes all of two seconds to run it.

here you go based on the info you provided me... obviously your weather conditions during the time of your shots will effect these numbers & this is based upon the 56degree @ night time current weather in my local with a 5.1mph wind (which you can totally ignore for now)....... but should get you close:

Thanks for the help.
