One implement covers about thirty years of a man's career. A first-year NCAA thrower, an Olympic finalist and a 45-year-old masters competitor all put the same 7.26 kg shot, which is 16 pounds. Nothing about the weight changes until his fiftieth birthday, and then it changes four separate times. Below is the adult men's weight with the rule behind it, and the masters ladder, which is the part almost nobody publishes in a form you can actually read.
The NCAA sets the men's shot at a 7.26 kg minimum for Division I, Division II and Division III, indoors and outdoors. The NAIA adopts the NCAA rulebook. USATF open competition, the World Championships and the Olympic Games use the same 7.26 kg ball. Once a man leaves high school, the implement stops moving. Every division's spec is laid out in college shot put weight.
NFHS Rule 6-10-2 puts high school boys on a 5.443 kg shot, 12 lb, which exists almost nowhere else in the world. International boys step through 5 kg at U18 and 6 kg at U20 before they ever touch 7.26. An American boy skips both steps and jumps 33 percent in one September. The full age chart sits in shot put weight by age. What he actually throws with that 12 lb ball is in average shot put distance for high school.
Masters men stay on 7.26 kg from M35 through M49. At 50 the shot drops to 6 kg, at 60 to 5 kg, at 70 to 4 kg, and at 80 to 3 kg. A best set at 49 and one set at 50 are not the same event. The women's ladder is in girls shot put weight.
Because the weight never changes between college and masters, video from one season is directly comparable to the next. Film a put from the throwing side and AI grades your block, release height and finish against men using the same 7.26 kg shot.

These are legal specifications, not estimates. The 16 lb figure is the one to remember, since it covers everything from a college freshman to an Olympic final.
