Reloading and Shooting 20-shot groups of .223 75 BTHP with Accurate 2460 and IMR3031. We are shooting a Tikka T3X .223 Remington at 100 yards. Afterwards, we examine the groups using the Hornady 4DOF ballistics application with the group analysis function. We also examine not only the extreme spread of the group but the mean radius.
