It does help in some areas, but it may make you to confident which is why I am always telling my son that this is only a game were you can get shot and not die. That is why I take him to the range to shoot the rifle. When I do he see’s how powerful a rifle is. When my son shoots the .308 or the shotgun he feels the power. The only weapon that he thinks that is close to a paintball gun is the 22lr rifle. Even the handguns are not the same. My son feels how the power of a .380 hand gun is or the 9mm. Lets not even think my son can handle a .45.
He tells me every time we go to the range that it is not the same at all.
I do think there is a point for airsoft for close up practice. The fast reaction to shoot.
