How do you generate the forces needed to crimp the brass around the bullet? I reloaded with my dad when I was a kid and used a mallot to beat the primer into place, so I'm not too worried about that aspect.
I would like to try reloading to make subsonic loads in .223 (for quiet pest removal) and possibly some hunting rounds in 7.62x39mm... all in small quantities. . . just to try it out and I don't want to spend too much money up front.

You have got a lot of good advice but I didn't see anyone directly answer your crimping question. The short answer is the Classic Lee Loader isn't used to produce a crimp.
The Classic Lee load is NOT used for Full Length sizing. It is for Neck sizing your rounds. You are suppose to full length size semi-autos, which is what most .223 & 7.62x39mm's are chambered in.
If for some reason you have a bolt action, Thompson Contender, or falling block .223 or 7.62x39 that you are reloading for, then by all means use the Classic Lee Loader. But for anything like that you don't need a crimp and so a "typical crimp" is not part of how it works.
Therefore if you want a crimp with the Lee Loader you need to resort to say a "stab crimp" where you use a pin punch or small screwdriver to pound the side of the case into the bullet. Yes, there were some commercial rounds that use to do that. It does mess up your ability to reuse the brass, but it is one way of providing a crimp with this set up. If that doesn't appeal to you then you need to rig up something the will push in the sides of the brass case to provide a roll crimp of some kind. At that point I would opt for an inexpensive press and a regular set of Lee dies in the calibers you are interested in.
I have a Lee Classic Load in 7.62x54R that I use along with my Lee 7.62x54R regular Lee reloading dies and my two reloading presses. I often will use my Lee Classic Loader to Neck size my MN 1891/30 bolt action rifle brass and deprime it. I will then use my powder scale to determine a charge, pour it into the primed case and use my press to seat the bullet and apply a crimp, if I want to. Rifles with tublar magazines (many lever and pump actions) and semi-automatics are recommended to have a crimp as are rounds with very heavy recoil (neither .233 or 7.62x39).
Hunting ammo that can be bounced around in a car or the filed is often crimped as well.
