Started in 1969 at age 15, had just bought a custom Springfield '06 (having saved my lunch, small chore, snow scooping etc., money for almost a year). Economics and accuracy were the drivers; Mom took pity on my, bought me a couple boxes of Remington ammo to have some empties, a Lee loader and components.

Became something of a compulsion, sort of most over-the-edge fly fishers who won't consider buying a fly.
