King Ghidora - you make good points about the gun industry and the variations in individual guns and ammo. My field was high end electronics and manufacturing controls there are quite different than "plain old steel" as we might call our guns. I am retired now so I just have to enjoy the shooting and leave the old high tech thinking behind. BUT, it is hard to unlearn the ways I had to live by day in and out over the last 40 years.
