Do you load for rifle? If so pistols are much easier.
In no particular order:
1. Carbide dies so you don't have to lube.
2. Taper crimp so you don't worry about case length.
3. As said above, seat and crimp in separate steps, you can do this with a three die set and a washer if you don't have a four die set.
4. You'll have to flare the case mouth a bit, especially with cast. Don't overdo it.
5. You usually don't need much crimp, might get away with just removing the flare.
6. Seater stem needs to match the bullet point/ogive, otherwise you can deform the bullet.
7. You might be able to develop a practice load that has the same poi as your full power load at a given distance if you use a lighter, slower bullet for practice. (don't count on it)
8. Before you load in bulk, load three or four rounds, pull the barrel, do the plunk test, make sure they fit the magazine. After all that, test fire them, if they function flawlessly, you're golden.
Good luck with it.
