Sort of sounds like some of the stories coming out about some newer +P+ rounds. Con Bon did change the way pistol ammo was made and marketed. Like some ammo now, it certainly had it's detractors. hot loads...ie Some Cor Bon, and other high pressure rounds. I guess it depends on what you are shooting it with. Super Vel was popular in the late 60's and early 70's for LE. confusing then and confusing now.
