well as a kid i started with a 16 gauge for bird hunting a model 11 Remington with 2 different barrels imp/full still own that shot gun and a Russian single shot too. my dear uncle Stanley was the designer and engineer at Federal Cartridge on all the crimps for plastic shotgun ammo in all gauges his name is on the patent too,he also helped pick out the colors for each gauge on shotgun ammo and that is why 16 gauge got purple so no one would mistake it for 12 gauge ammo. Federal along with my uncle choice the colors > 10 gauge brown,12 gauge red,16 gauge purple,20 gauge yellow,28 gauge brown,410 gauge red i got to see all this shotgun ammo before the public even knew about these colors for plastic shotgun shells. as a 14 year old kid shooter/hunter i had no ideal how big a deal this really was in the world to shotgunners all around the world.
