I love this application and want to be able to use it in a bird hunting situation but have many questions if anyone is familiar please. I filled in numbers i know that are accurate and the proceeded to sight my rifle in at 25 yards. Then went to 75 and shot a few goups. I use the SR pro reticle and choosen scope. My 75 yard group is off about 14 yards looking at the mil dot lines of scope.

Projectile Name= JSB Beast they are not on list, so i renamed and changed pellet weight to 34.00 gr
Weight= 34.00
BC= ? This is my question, because i can the make the group match the scope line if i enter 0.058
Muzzle=935
Sight Height= 2.0
Far Zero=25 another question, I sighted in at 25 yards, is that the number that I enter?
Clicks/moa 4.188 came up from my scope. Hawke 30 series 8-32-56 with sf and sr pro. Is this correct?

Should I be changing the BC to make the graph and information correct to my setup? AM i doing this all wrong?

By the way the gun is Daystate Wolverine 2 HP .22

I have the following JSB pellets Heavys, Monsters, Beast
I feel like the Beast pellets are the most accurate and quietest at any yardage to 75 yards and still shoot at a good speed. Should I be spending more time with another pellet that shoots flatter with less drop? 

Thats for any help. I am new. Just addicted and love the tech stuff with the ballistic charts and graphs and want to be to know where my pellet will hit with confidence out to about 120 yards
 
whitetail17 I think you have all the main parameters covered. A better BC would be .046 according to HAM report http://hardairmagazine.com/ballistic-coefficients/. I guess if your zero'd at 25yds that would also be the far zero. If your shooting out towards 75yds you might consider a further zero, maybe 50. I enjoy shooting out to 80 alot so I zero my three guns at 60. That might correct some of the difference your seeing. Maybe not.
As far as the reticle and the Click/moa. My Hawke SW it 1 click = 1/4 MOA which is 4.000 click/MOA. If you have the desk top version of Chairgun you can right click on that box and it'll give you the options to select you scope's click/moa. If you don't have the desk top version I can check it on mine if you'll tell me what it states on top of the turret. Seems like the mobile app should give you the same options. Let me know if I can help further.

Whitetail,

The desktop version of ChairGun has a BC calculator that you can use for BC. You will need a chrony. Shoot a shot string with chrony close to muzzle. Using the average velocity at V1 in the calculator. Shoot a second string at 50 yards with the chrony set up by the target and use that average velocity at V2 in the calculator. The BC calculator in ChairGun uses a mathematical formula taking the difference in velocities at the two locations into account and will give you a better BC number for you to use. Different gun/barrel/pellet combinations result in slightly different BC numbers. But the biggest problem is what Jimmy mentioned above regarding 1 click= 1/4 MOA = 4.00. Also consider or investigate how your reticle in your scope is laid out. Some Hawke scope have MIL reticle and MOA turrets so this needs to be accounted for, especially if you are a professional shot. (In Alabama this means you can shoot a knatt off a Bulls Ass at 100 yards!). It's a rare skill that I personally do not pocess!

The clicks wont effect the hold over locations. If you have the wrong clicks selected it will only be a problem if you use the turrets to adjust for distance instead of using hold over in the scope. It doesnt matter what magnification hes shooting at as long as he changes the app to show hold over for that power. So make sure you have the app set to the power you are shooting at. Also I agree with Jimmy that you should be using a 40 - 50 yd zero if you are shooting out to 75 yds regularly. Thats just personal opinion and you can zero for whatever you like but a 25 yd zero is pretty close if you shoot longer distances allot. If its still off with the magnification set the same in the app as the scope then adjust the BC till it matches.

"Centercut"The Ranging Magnification on the SR Pro Hawke is 8x. Try using that. I think it might be called Calibration Magnification in ChairGun Pro. So adjust your scope to 8x and try using your holdovers. You could also go to 16x and the holdovers will be double. For example, two mildots at 8x would be 4 mildots at 16x.

One mil will equal two mil at half the calibrated power. 

One mil will equal a 1/2 mil at double the calibrated power.

Not exactly sure what you are trying to say here so if I am misunderstanding my apologies but I think you have it backwards if I am not misunderstanding.

If you have a scope that ranges at 10x and 60 yds is at the first mil dot at 10x the correct hold over will be at half a mil dot if you drop power to 5x. If you go to 20x then the hold over for 60 yds would be 2 mil dots.
