YanYatCheng 96 Posted March 1, 2018 I've been using .300WM from RHS with Advanced Ballistic for a while with the help of ballistic table and now decide to move on to ballistic computer. Unfortunately, there isn't a right ammo for me to choose with default .300WM setup, so I need to setup all the data by myself from the start. So far I've got the C1 data and other stuff, but I am now stuck on calculating drag and the computer never calculates the right data. Is there any sniper expert that can help me with setting up AtragMX? Share this post Link to post Share on other sites
selangarp 0 Posted March 9, 2022 Has anyone tried it with an M14 and a standard 7.62mm 20Rnd Mag? Share this post Link to post Share on other sites
Gurzuff 0 Posted March 9, 2022 Open the AtragMx and Atmsphr columns, select Default and Done. Open Gun7.62x51mm M80 caliber GunList. [Manual]. Select E in the upper right corner. [Manual].Open Gun column, check and update Bore, Rifle Twist, and Done. Select M (Metric Unit) in the upper right corner. Open the column, check and update the Muzzle Velocity, Zero Range, and Done. If you do all of this correctly, you will understand how to install the new ammo in the same order. It's really not difficult. You need to know the sequence of operations and not make mistakes in the functions. Share this post Link to post Share on other sites
