With the ammo situation the way it is I'm thinking about it. I know absolutly nothing about it, but I've a good mechanical aptitude. I understand a good dial caliper is something one would need and that I have, everything else I would need to purchase. How much $ should one expect to spend to get started (40 s&w, 44 mag and 300 savage)? Can any one recommend a good book or video? Thanks... Rick
