Full Power Ammo

These are our cartridges that are considered full power loads. This does not mean that they are particularly hot just that they are not loaded down for Cowboy Actin competition. All of our rounds are loaded within SAMMI specifications and will work in modern guns, but as always make sure check velocities before firing in older guns. Also be sure to check the velocities to ensure that the load you are purchasing is right for what type of shooting you plan to do.
