## What is Chairgun Elite Ballistic Tool+?

This is a smart ballistic calculator for long range shooters. It helps shooters calculate hold overs, and scope settings necessary for long range shots. Works with large caliber and airguns.

This app is using temperature, altitude, humidity, atmospheric pressure, distance to target, target speed and direction, coriolis effect, slope angle, cant and your rifle configuration for calculate optimal vertical, horizontal and lead corrections.

Features:
• Can use G1, G2, G5, G6, G7, G8, GA, GC, GI, GL, GS, RA4 and even custom drag-functions (built-in editor), and can calculate trajectory without using ballistic coefficient!
• You can select reticle from the list (around 2600 reticles! including reticles from Carl Zeiss, Nightforce Optics, Kahles, Vixen Sport Optics, Premier Reticles, Primary Arms, Schmidt and Bender, SWFA, U.S. Optics, and Vortex Optics) and see hold overs at any magnification (see list of reticles supported here http://jet-lab.org/chairgun-reticles)
• List of bullets: around 4000 cartridges database, more than 2000 bullets database, around 700 G7 ballistic coefficient bullets database, around 500 air rifle pellets database includes American Eagle, Barnes, Black Hills, Federal, Fiocchi, Hornady, Lapua, Norma, Nosler, Remington, Sellier & Bellot, and Winchester (see list of bullet/cartridges supported here http://jet-lab.org/chairgun-cartridges )!

### 5/5 — Best thing since Strelok

*2026-08-14*

Since Strelok went away a few years I was looking for an alternative. I’ve used Chairgun as a paying customer for a long while now and it is at least as good, if not better than Strelok.

### 5/5 — Needed a great app.

*2026-06-23, version 7.9*

Chairgun has been an awesome addition to my match shooting. Love the reticle option. Load your data and start shooting. Great job on the app.

### 4/5 — Subscription AI

*2026-06-05*

A highly functional product, more than I require for an air rifle.  However, It appears free but some functions have automated subscription attached, with no option but to continue or close it down!

### 3/5 — Good app but missing important reticles in MOA

*2026-05-26, version 7.9*

The app works well but is missing the reticles for the ATHLON HERAS SPR 6-24×56 APLR9 FFP IR MOA
&
HERAS SPR 6-24x56 APLR7 SFP IR MOA
Which are popular for Field Target in the US.  
The subscription is not worth the cost if your reticle is not available.

### 4/5 — Please add vortex razor gen 3 4-24

*2026-05-17, version 7.9*

Awesome app, seems similar to strelok that it’s familiar but it’s missing some newer optics. Would be awesome to see the new vortex scope in there!

### 1/5 — Why was there no differentiation of Burris Eliminator 6 X177?

*2026-05-10*

Why was there no differentiation of Burris Eliminator 6 X177?

### 5/5 — Excellent Ballistic calculator

*2026-04-14*

It gives absolutely accurate solution,

### 1/5 — Paid for it on another computer, cannot use it without continuous re-payment via subscription

*2026-04-13, version 7.8*

Charge for it then extort re-payment via subscription.  Considering computing devices are obsolete every 2 years, it's a total rip-off.  Vultures profiting off the ban of Strelok Pro.

### 3/5 — Give me a one time payment option.

*2026-03-23*

It’s great. It’s everything I want in a ballistic app that cant be acquired from the comrades but for effs sake just make it a one time purchase. $20 and I’d be all in. This nickel and dime over time is dumb. I guess that’s what you get when it’s not comrade owned.

### 5/5 — Güzel bir uygulama

*2026-02-11, version 7.7*

Garmin xero uygulamaya bağlayabilirsek çok güzel olur
