Congrats and welcome to reloading if you're new to it.
Chances are you won't settle on just one recipe for plinking. Part of the fun of reloading is experimenting with different loads and combinations. Usually this experimenting happens because of component availability (or lack of) forces you to buy different bullet weights and powder. Also every gun and person is different, what I shoot well you may hate.
Check the component prices at your local porn shop, sometimes they have the better prices, especially for powder and primers. Unless you buy powder and primers in very large quantities it's usually cheaper buying locally because of the hazmat shipping fees. I usually find my plinking recipes vary depending on what powders I can get locally and what bullets I can find that are in stock.
With the current surge in gun sales and hoarding it's getting hard to find dies and bullets. I currently have a bunch on backorder at Midway.
