Just trying to see if I understand the concept. Under-gassed guns have issues cycling, because when the pressure wave finally gets to to release the locking portion of the action, too much gas has left the system and it doesn't have enough "oomph" to push the bolt back fully, or stovepipes. Which is to say, once the bolt is unlocked, the system functions identically to a straight-blowback system.
In an over-gassed setup, this all happens too soon, causing the bolt to get thrown back with much more force than necessary, increasing felt recoil and generally causing the gun to jump more when shot.
Am I correct in this?
Reason I ask, is a few days ago I was at the range with someone and he was shooting a mini-14, brand new, getting it sighted in and breaking in the barrel. This gun was flinging brass 20 feet before hitting the ground. Sometimes it would arc so high to would hit the rafters of the shooting pavilion. And this was all intentional, according to the gun owner. It apparently made the gun "shoot smoother". I just don't understand how it is possible.
NES, Educate me plox!
