Tactile Tip Of The Week.
Hi everyone. This is a short posting but something that I have discussed in the past but I often see the terms misunderstood in posting at times. The two terms are in relation to analysis of the bullet strikes on target when either single shots or multiple shots are rapidly shot in sequence.
The two terms are , “groups” and “dispersion pattern”. Quick examination of both:
“Groups” are often referred to as how close each round is the the others. Groups are used to examine each INDIVIDUAL round shot. This is typical in slow fire and also when sighting in the iron sights, red/green dot optics or magnified optics. The goal is to have a precise way of ensuring the sights are in proper alignment to ensure proper zero. No time limits involved and each shot is independent of the others. The white picture attached is an example of a “group” I shot using a Glock that had new XS sights installed. I used the bottom of the circle for consistency and the very top of the Big Dot placed at the bottom of the circle for consistently at 10 yards. There are 5 shots in the “group” and as expected , based upon how I shot each round described above, the group is where it should be placed to, to ensure proper sight in.
“Dispersion pattern” is the placement of multiple strikes of the shots fired in rapid succession in tight time limits. This is akin to how we shoot in close quarters combat shootings. In the attached picture , I shot a dispersion pattern with a 1911, 45 ACP, 230 grain hardball ammunition.The time the dispersion pattern was delivered in along with the distance using the primary hand only is indicated in the picture.
Anyway, just a brief explanation I hope clarifies the issue. Have a great day.
