What load data should I use for the Triple-Shock X-Bullet?
Loading data is being created for the Triple-Shock X-Bullet. Until this data is made available, we suggest you use standard X-Bullet data. In some cases, pressure will be reduced, allowing you to add a couple of grains (in 1/2 grain increments) of powder to the maximum loads listed, while watching carefully for signs of pressure.
