On two specific shows the 5.56 is put up against the 7.62x39, 6.8 SPC and the 6.5 Grendel. The measuring stick is knocking down a steel plate silhouette. Every 5.56 shot is at the 6-7 0'clock low, low, low. The competing calibers are all at the 12-2 o'clock position and very high. I have no doubt as to Mack's skills so that should rule out random shots. Has any one else noticed this?
