A competitor reloads a shotgun during the 2018 USPSA Multigun Championship in Boulder City, Nevada.. Multigun, Multi Gun or Multi-Gun, often also called 2-Gun or 3-Gun depending on the types of firearms used, are practical shooting events where each of the stages require the competitor to use a combination of handguns, rifles, and/or shotguns [1] Multigun has a lot in common with ordinary IPSC ...
Hyperdynamic precordium is a condition where the precordium (the area of the chest over the heart) moves too much (is hyper dynamic) due to some pathology of the heart. That means a forceful and hyperdynamic impulse ( large amplitude that terminates quickly) can be palpated during physical examination. [ 1 ]
All the MPIs of gun B are on the target area, whereas those of gun A are well spread. The conclusion in this case is that gun A has good consistency, but poor accuracy. Gun B has poor consistency, but good accuracy. [citation needed] Figure 3: The mean points of impact for guns A and B (case 2) A more realistic possibility is shown in Figure 3.
In anatomy, the precordium or praecordium is the portion of the body over the heart and lower chest. [1] Defined anatomically, it is the area of the anterior chest wall over the heart. It is therefore usually on the left side, except in conditions like dextrocardia, where the individual's heart is on the right side. In such a case, the ...

The gun's short recoil operating system causes the barrel to reciprocate, similar to the M2 machine gun. This combined with a gas system to minimize recoil balances positive and negative recoil forces, allowing a gunner to fire a round with significantly greater energy but with the recoil profile similar to a 7.62 mm round from an M240.
