Tonight I went to a class by one prepaid legal defense companies. They brought up a past case, one thing that made a case hard to defend is he had different brands of ammo in his magazine. who's spent brass is who's same caliber. This got me to thinking, I do carry some hand load ammo, and I am sure that it is all mixed head stamps. I would hate to ever have to defend myself with a firearm and if I did I would surly want to make it as easy as I could for law enforcement and lawyers to sort out the details.
