I use a three die set for most of my reloading. I use a progressive for 45 ACP. I use a single stage for everything else. I can go through 200 rounds in a single competition. Plus I try to shoot once a week on my own. There is another 50-100 rounds. So I probably shoot 400 to 600 rounds in a month. That is just in my competition guns.

When I shoot at an IDPA or USPSA match it is not uncommon for me to have two rounds within an inch of each other on 10-15 yard shots. And that is shooting pretty fast. That is plenty accurate for me.

Setting a crimp/seat on one die can be tricky if you don't understand that your not crimping... crimp is a bad word to use since it implies your pinching the case into the round. The case should never be "crimped" smaller than the original sized diameter.

Some dies offer rolling capability and even that is often waaaaay over done.

A roll "crimp" should only be rolled .010 or less into a canelure bullet only.

Bullets are held in by friction only never by the crimp. Roll crimping on cannelures prevents bullet setback or the bullet pulling out on recoil.

Taper crimping returns a belled case mouth to the original sized diameter.

Reducing the diameter of the case mouth by "crimping" below original diameter actually loosens the bullet and then bad things occur

Cuz some folks are just to cheap to buy a three die set!

You can set the combo die to seat, but not crimp. then when all rounds are seated, you can back the seating stem out and use the crimping shoulder in a separate operation.

PITA, but if you're going for cheap it works.

As I use a progressive press, I just get a separate taper crimp die.

Ideally a 4 die set is best.
But not all 3 die sets are created equal.
