I’d say that the obvious answer is that it holds everything together. All of those dimples in the ring could be “shear points” where the ring will fracture and fly apart when the sabot starts to seperate as it leaves the barrel. This being a rifled barrel, there is a tremendous amount of centrifugal force acting on the projectile. I’ll bet that the metal is precisely calibrated to shear with a certain amount of stress, but is strong enough to hold things together during handling. Of course, I could be completely off base too…


I have confirmed that you are correct AKMS. That is exactly what that gasket thing does. Thanks so much.


The Alberta Cutter has some serious competiton. Great job, Jason.
