"Deformation occurs at ignition and early acceleration."
Rocketman, I have to disagree with you about that especially with todays plastic wads. Shot is still in the wad and deformation would not occur until after it left the barrel
Probably merits a topic all its own. I don't think all deformation on ignition is eliminated by plastic wads. Reduced for sure, but not totally eliminated.
And why would deformation occur after the shot leaves the barrel? Pellets running into each other?
Interesting subject.
