Hi Guys I downloaded the shooter app last night I put the info in but im not quite sure what that represents when dialing where it says elevation does
U5.7 moa, does that stand for 5.7 inches ? also says U23 clicks that's for a 0 at 200 meters target at 400 so do I count 23 clicks up or as you can see on the scope 1 full turn would represent 16 what ?

It means up 5.7 minutes of angle. Looking at your scope dials they look like 1/4" clicks so every 4 clicks is 1 MOA. With your scope on 0 5.7 MOA would mean twist it to half way between 4 and 6 then 3 more marks.
In round figures 1 MOA=1inch. (MOA stands for minute of angle)
So 5.7moa at .25 per click on your scope is 4 clicks per 1moa, 5.7=23 clicks
Make sure (if you haven't already done so) in FIREARMS the setup for your rifle/scope is set to IPHY (inch per hundred yards) and not MOA. Your scope is 1/4" per click not 1/4 MOA per click. Not that there is a huge difference 1 MOA = 1.047" at 100 yds. And set your click to 1/4. Both settings are in the firearm edit and are together. You probabaly have already set the 1/4. Using SOLUTION it will tell you the MOAs and CLICKS you need to come up from your zero range (200) to your desired range.
Something doesn't look right. A quick glance says you have a 200 yd zero but the -23.7inches/- 5.7MOA path would relate to a 100 yd zero calc. Mmm let me find go and fire up Shooter.
One full turn on your scope looks like 18 IPHY = 72 clicks. You also mention 200 metres. What range have you sighted in at? Metric or Imperial distances?
Ignore first bit, your calcs look OK.
-23.7 inches at 400 yards = -23.7 divided by 1.047 divided by 4 (hundred yards) = 5.659 MOA.
I understand now well the clicks anyway :) .zimmer i sighted in 2" high at 100 so should be very close to a 0 at 200 , theres a good chance i haven't got the app setup quite rite some things i haven't filled in yet like the bullet length or barrel twist , which is 9 1/2 but im not sure how to put that in ,the firearm data it asks barrel twist 1 in ? would that be 9 ?
sight height iv got 1.000
lead unit is MOA
elevation turret grad 1/4
sight offset 0.000
Thanks for the help
Just out of interest are you running an Apple or android fone?
Don't worry about the bullet length or barrel twist, they are not used in your calc only I think for corrialis (mmm spelling) effect which is the distance the earth spins/moves whilst you bullet is in the air - artillery stuff ha ha. Corrialis should be turned off by default.Quote:

You can also enter a zero offset in for your 100yds zero 2" high. Edit looks like you may have applied that offset?
Biggest learning curve is the atmospherics. Have fun.
I have 0 in sight offset & i don't actually see where it has asked me for my zero distance ? its a iphone 6
iv got the BC 0.3590 then it asks for minimum vel is that minimum muzzle velocity ? lots of questions !!!
On your scope top turret there is numbers from 0-18 by the looks. If you have sighted your scope and your number '0' is above that line/mark then all you have to do is twist it around to whatever your distance says.
eg if you are shooting out to 350 all you have to do is twist that turret around to 4.1 on your scope.
Each number is 1MOA....4=4moa....9=9moa etc etc
Leave minimum velocity at 0
If you up load from the bullet library it should do it for you.
Under where you enter your zero it says something like zero height, that's where you enter 2 inch if your 2 inch high at your zero, (which might be 100)
All this is under your round not firearm. Edit the round.
Check with the scope maker, to weather or not each click is 1/4 inch or 1/4 moa. I have a s2 bigsky (sightron) that says 1/4 inch but sightron says it's actually 1/4 moa.
Your twist would be 1:9.5 I'm pretty sure you have to enter this and bullet length to get a solution.
If you google shooter app manual you will find a manual online.
Hi Borax
Good posting with pics
The min valUe for BC is to allow you to enter Several valUes of Bc. It changes'slightly with velocityspecially down close to the speed of Sound. You Can enter extra bc Values by touching the green PLus button. You w0nt need to do this for ordinary hunting.
straight below the BC area in the bullet setup <Edit> is Zero Data.Thats where you enter yourZero range (l00m) and Zero height ( 5cm) if using metric units .
In an earlier posting I said this was needed for Coriolis Effect which is not correct. In actual fact it is used for Spin Drift. If you wish to use Spin Drift you need to enter this data and turn Spin Drift on. I don't bother using it for closer ranges and usually enter my barrel twist because I know that off the top of my head, but don't bother with projectile length. If I remember correctly, from the old 303 target shooting days the correction was something like 1.5 MOA at 900 yds. Should run it thru Shooter I suppose :-)Quote:

The other things is correct as it is…

It will ask you during the setup of the rifle, if you want to correct it you need to go to your rifle menu, click edit and select your rifle… follow the "prompts"Quote:
