The lee loader comes with a flaring tool.
The little paper that comes with it that specifies dippers and stuff is really bad, I'm looking at the 357mag one right now, and I'm not sure I'd have started reloading if I went by this data.
(For instance, the powder that gives the most velocity with a 158 grain jacketed bullet is listed as unique, 7.8 grains.) That's waaaayyy down the list in most manuals I have...
10 grains of blue dot is safer, and just makes more sense, and isn't listed, because it would take more than a scoop of powder...

Weak, inflexible, and it seems the only way to increase power is to change bullet weight and powder.
Yeah, the paper I got is prolly ten years old, but I'm sure it's still pretty conservative. Which is a good thing starting out, but you are still gonna need a scale and trickler eventually....
And at least the less than $10 .357 mag caliber specific loadbook.
