RCH; we DON'T WANT to keep the kids out. I started handloading when I was 14. Let the little darlings in. We shall corrupt them with muzzle velocities, make them learn math to figure out trajectories, have them bend over and pick up their brass and ours, learn the wonderful smell of Bullseye powder.
Let their little hands get callused from working the progressive reloader; perhaps daddy, er, ah, WE can break out the bullet molds from storage and have them learn patience and the proper way to fill a mold.
Yeah, heck don't keep the little darlings out; they are our future, and if we don't let the gun bug bite 'em, who will? Walt
