I was loading some 9MM this weekend, some Remington 125 gr. Golden Sabre's, and found a unprocessed lead core in the box. It weighs 90 grs., so that makes the jacket weigh 35 grs. I don't know how these bullets are made but I would guess the jacket would be formed then the lead core inserted and under pressure the core fills the jacket and the nose is formed. You can see from the pic that the core is longer than the finished bullet, it would be interesting to see them made.
