I was is hand cycling some 30 caliber carbine to my M1.
On my third mag my wife asked me what is that noise and I said I'm testing my magazines for function in one of my rifles. She said you're going to have another accidental discharge like you did in 2003. I said no way I've got the safety on. I looked at the bottom of the ammo in every one of them had an indention in the primer. In the picture below you can see the ones that I ran through or on the bottom compared to the ones on the top and every primer that I ran through has an indention. I don't think I will be testing my magazines by hand cycling anymore. Haven't gotten out to the range do this covid. But as you can see this looks dangerous.
