Shotgun Slug selection

[u/Agile-Delay-8770]

Looking for some cheap ish shotgun slugs for range practice so nothing like federal but also don’t want it to severely gunk up the inside of my gun like I hear with some cheaper options.

Anyone know of some good ones that fit the description?

Challenger, Score, and Mili. I shoot all three of these and they are good for the price.
