Re: Do manufacturers crimp all factory 223 ammo?
I would love to take a tour of a bullet manufacturing plant as well. My father was the head of engineering for Daisy BB Gun for several years, and I was absolutely fascinated to learn how they make BB's. I was also fascinated to learn that most of the shotgun shell manufacturers buy their shot from Daisy.
The first time my father gave me a tour of the Daisy plant, I had all of my childhood questions answered in a single day. I felt like a 30 year load had been lifted off my shoulders when I found out why there was a flat spot on BB's. When I was a kid, we thought they melted steel and dripped it into a big tub of water to make the bb's. We figured the flat spot on the BB came from the BB resting on the bottom of the tub before it had cooled completely. When my friends and I were 10 years old, we had plans to write a letter to Daisy to ask them to use deeper tubs of water so the BB could completely cool before landing on the bottom. For some reason we never wrote the letter.
Come to find out, BB's are made from HUGE spools of steel wire. The wire is fed into a cutter and a small piece is cut off and dropped into a giant round press. The press is about 3 feet in diameter and it has a groove cut into it that spirals down to the center of the press.
The top portion of the press rotates opposite of the bottom portion of the press, forcing the piece of wire to roll down that spiral groove to the center of the press. By the time that piece of wire reaches the center of the spiral, it has been rolled into a round BB. At the center of the spiral (center fo the press), there is a hole drilled for the BB to fall through and exit the press. The flat place on the BB is simply the very tip of the piece of wire. To make the different shot sizes, ie: #4, #2, BB, BBB, etc., they just use larger or smaller diameter wire and feed it into a press that has a spiral groove the size of that particular shot size.
It was that first tour of the Daisy BB Gun plant that I had my moment of discovery. Entering the plant I thought I knew everything, and exiting the plant I realized I knew nothing.
