I hate to rain on your parade, but right now may not be the best time to take reloading up. Powder and primers are hard to come by and prices are outrageous. Where just a couple of years ago a box of 1000 primers was around $30-40, now they're anywhere from $75-100+. That's if you can find them.
Powder is pretty much in the same boat. Before you make a decision, you might wanna do some searching on what you need in the way of powder and primers, current availability and pricing.

For the last 2-3 years I've been buying factory ammo in bulk for the more common calibers and saving my dwindling supply of powder and primers for the more expensive and harder to find calibers.
I consider .38 Special to be a common caliber. Might wanna check into bulk pricing for factory ammo. Start at Ammoseek.com.
