For newbies or oldies

So relatively new to long distance shooting and don’t have a spotter. But once you know your zero at a specific range..(highly suggest 200) and you know the bullet you are going to use (never change btw) this app has allowed me to very accurately dial in my holds up to 450 yds with my JP 15 shooting 5.56..
Have to be within 2” of accuracy to the calculations... I believe it would be dead on if I had the exact correct velocity of my rounds, but just going with what the box says. Also the huge preloaded ammo selection is awesome.

Most expensive app purchase ever, and paid for itself in the ammo I’ve saved!

Great Improvements Made

I was reluctant after reading the reviews to download this app, but after looking at the update history I decided to give it a try. It has worked flawlessly and is very easy to use, including with the Apple watch.

This app developer has worked incredibly hard to address all the negatives brought up in past reviews. Every update is something major that makes a huge improvement in functionality. A year ago I wouldn't have recommended it, but today I say buy it with complete confidence.

Love this app

I have paid for and downloaded four ballistic calculators and the SBC app is hands down the best one out there. Intuitive and easy to use, save your favorite reticles for quick access and the birds eye view of your surroundings is really cool and useful. Don’t waste your time and money on any other app.
