My Dad started me when I was 5-6 years old. That was before plastic shotgun wads appeared, and he shot a lot of skeet. He made up a multi-wad stack of cardboard wads as an example, and asked me to make up 100 just like it. I watched him load those up and he then took me along the next time he shot. That's all it took. I can count on one hand, with a couple of fingers left over, the number of times I have shot rifle, shotgun or pistol factory ammunition (other than 22 RF)in my life.
