Arma Dynamics, a training company started in 2013, has posted up a veritable treasure trove of useful zeroing information and targets. Knowing that many shooters often do not have access to long-ranges for zeroing their weapons, Arma has graciously curated a selection of targets for various range conditions and graphic representations of impacts using various zeros, barrels, and loads.
All too often, shooters do not know the appropriate zero for their weapon system or opt for a zero that they are familiar with versus the one best suited for the choice of weapon, caliber, and barrel. Arma has provided a fantastic graphical reference for common military loads across a variety of barrels. Velocities and various other information is disclosed, making it easy to correlate to personal non-military choices.
Targets are also available for a variety of conditions including zeroing for distances other than what is available. For me, the most useful is the 50 yard zero for shooting at 25 yards. The two closest ranges for me have 25 yard maximum distance and my long-range is an hour away. The targets are extremely handy when one say has a 3-gun event the next day and their new baby kept them from the range (not that this has ever happened to me).
*Author’s disclosure, I am personal friends with one of the trainers of the company. However, they did not refer the targets to TFB for publishing – it was a random encounter via another source.
