Hello all,
I've been wondering about the way the way the bolts lock in firing position when there is a plunger ejector.
Unless I'm mistaken, when the bolt is going forward, first it will put the ejector spring under tension, go on moving forward and straight, and then it will be allowed to turn, locking into firing position.
Given the shape of the bolt carrier, in the part where the bolt is going forward with the ejector spring under pressure, the tension will be redirected as a rotary tension (the bolt tries to rotate early)
As the string is very stiff (if you're trying to lock it by hand, you can't lock the bolt without some momentum, it's too strong to overcome), this means that at the instant before the bolt is allowed to turn, there's quite a lot of tension trying to turn the bolt. Isn't that prone to rounding off the edges of the locking teeth, possibly lowering the life span of the rifle? (maybe it is intended to be rounded off, without altering the action?)
Thanks!
Pierre
