1. If you're new to reloading, a single stage press is more forgiving and easier to learn if you load in small batches. Go purchase a reloading manual if it doesn't come with your reloading kit.
2. Unless you shoot at a club where used brass is plentiful, you'll spend at least $.06 for used brass.
3. The 38 Super handload uses bullets under 147 gn under .356" dia. .357" and .358" dia bullets are not recommended. It's fun to see 95 gn .380 ACP bullets zip downrange at supersonic speeds. Nylon coated lead bullets work just fine in my pistol, though i'd suggest against softer lead cowboy bullets.
Costs:
1. Used range brass: $.07 each
2. Small pistol primers: $.022 each
3. .355" dia bullets: $.08 to $.20 each
4. Powder charge: $.03 per charge
So if you're on a budget, shooting .38 super reloads start at 18 cents per round.
Compare that to a WWB store bought ammo cost of 33 cents per round.
