Figure 4. Variation in the mean of deviation values.

The analysis of the obtained results shows that when firing with a
contactless suppressor, the value of the average group deviation along the
abscissa axis is lower by 1.87 mm, and its numerical value in relation to the
ordinate axis is 3.58 mm. This shows that when shooting with a contactless
suppressor the accuracy on the horizontal axis deteriorates, while on the
vertical axis, the opposite trend is observed.
When the average deviation of the two groups against the dispersion
axes is graphically depicted, the ellipses shown in Figure 5 are generated.
