I am currently reloading for and shooting a 12 gauge. I see the plastic hulls are beginning to fatigue at the corner folds and that created a question in my mind. Will the fatigued plastic be easier to open, when fired, creating less back pressure and a slower shot? The question might not be worth pursuing but I would like to know if anyone has seen data on speed vs number of times a hull has been reloaded.
Thanks in advance for your time and effort.
