Time to put a progressive reloader on the work bench! I have been reloading with my son since he was 5. He's now 11. If I'd allow him to do it by himself, he could whip up rounds with the best of them. What I'm getting at is your kids are sponges for information and its a lifetime learned skill. If they are at all interested, share a little time at the bench with them. I actually kept the first 50 shells of .357 he primed for me 6yrs ago......I found them in the safe a few weeks ago. Was kinda cool.
