It is not a practical exercise!

The Federal .22LR hollowpoints I buy by the 550 round "brick" at Wal-Mart cost about exactly what primers alone for the centerfires do.

Yeah, how is not the hard part.

I see this come up now and again. Beats me WHY anyone would bother to consider it even if they have an odd ball like a .25 Stevens RF.

Does anyone know how to reload rimfire ammo?

This question always generates a lot more heat than light, so be prepared for the aghast community to rise up and call for a new law.
Sometimes the old dent is removed, sometimes not, but the work hardening of the brass must be kept in mind. Normalizing at less than aneal temp is advised after sizing.
If the cartridge is a heeled design, either a stab crimp or a scheme similar to the Lee factory crimp may be used. For single loading it may be expedient to skip the crimp. Revolver and derringer ammunition usually needs a good crimp to prevent bullet pull.
Spinning the primer slurry into the rim can be avoided by smearing it in place through the mouth of the case, but this is a tedious exercise, and usually uneven. It is in this step that most unexpected explosions occur, as the primer slurry dries on the tools and in the mixing container.
Primer formulas, even including the use of match heads, are all over the web and in the literature. There have been some well covered disasters with amateur chemists, so a little caution is always advised, but you know that. Avoid the Darwin Award.
