First, in the repulsion distance, in Examples 1 to 4 and Reference Example 2, the rebounding direction of the shooting bullet was constant, but in Reference Example 2, the rebounding direction was not constant from right to left. And, in the case of Examples 1 to 4, as the impact resilience becomes smaller,
As the hardness became softer, the distance bounced from the aluminum plate T was shorter and the rolling distance was also shorter. In the case of Reference Example 2, the distance bounced from the aluminum plate T is the same as that of Reference Example 1, but the rolling distance is longer.

Met. Then, in the case of Examples 1 to 4, as the impact resilience became smaller, as the hardness became softer, the height from which the aluminum plate T bounced was lower and the rolling distance was shorter. In the case of Reference Example 2,
The height of bounce from the aluminum plate T was higher than that in Reference Example 1, but the rolling distance was shorter.

Nitrile rubber having a hardness of 5% and JIS-A of 28 to 57, impact resilience of 10% to 13% and hardness of SRIS-C
Since the shooting bullet was composed of 22 to 40 nitrile rubber sponge, as can be understood from the data of FIGS. 3 and 4, the repulsion distance, the bounce height, and the movement distance were small, so the target was hit. It will not bounce back and hit the shooter afterwards. Even if the shooting bullet of each embodiment hits the target or the like and then bounces and hits the shooter or the like, the resilience is great and it is safe.

なる。Further, since the shooting bullet of each embodiment does not rebound so much, it is not necessary to cover the shooting bullet with acrylic or glass so as not to hit the shooter, so the target is easy to see and the installation cost is reduced. It is possible to increase the degree of freedom of layout. In addition, since it hits a target or the like and falls to the vicinity of the target or the like to stop, the collection can be easily performed. And since it is a spherical shape, the part where the shooting ammunition falls is constant, and by forming a recovery groove etc. by slightly inclining from the part where this shooting ammunition falls, recovery of the shooting ammunition can be made easier.

And the compression set (22 hours at 70 degrees Celsius) is 5% to
Even if it is 55%, the same effect can be obtained. However, since the gun G shoots, considering the elasticity and hardness of the shooting bullet, the impact resilience is set to 10% to 13%, and the hardness is JIS-A.
It is optimal to set the compression set to 28 to 57 and the compression set (22 hours at 70 degrees Celsius) to the range of 7% to 35%.

Needless to say. Although the example of the spherical configuration has been described, it goes without saying that a shape other than the spherical shape, for example, a conical trapezoidal shape or a cylindrical shape may be used. Further, although the size has been described as an example of 12 mm, it goes without saying that the size is not limited to this.
