You don’t hear a lot of talk about it, but I use Shooter. It’s very intuitive and simple. It doesn’t have the best bullet library so sometimes I have to manually enter a projectile. I have found if you enter the data correctly it delivers good solutions. Last week I had some people at the range and I was showing them how it could be pretty easy to do and we set up several rifles, shot true zeros while using a LabRadar so we had real velocities. We then measured height over bore and entered it all into Shooter. We then compared the density altitude from my Kestrel to Shooter using the weather station and they were both within 200 feet so good to go. We started verifying the rifles from 300 out to 1200 yards at 100 yard intervals. Worked flawlessly and matched my Kestrel data. Good data in and reliable solutions out. I’ve done this exercise more than once and it’s always worked.
