The test involves firing an initial five-round group, followed by a 30-round magazine dump into the dirt, and then another five-round group to assess any shift in point of impact due to heat. The results indicate the barrel's heat treatment and stress relief are effective, as the second group's center remained consistent with the first, despite external factors like wind.
