I'm trying to get all that I can out of my media. Right now, it's starting to look pretty dirty. Has anyone ever tried to wash it? By that, I mean just rinsing it in water.
Do a google search for crushed walnut shell. You'll find many sources. Local feed stores sometimes have ground corn cobb, but I find that fine-med. walnut cleans faster & last longer than corn cobb. At $1/# or less, is a decent price IMO, & 50# would last a shooter 5yrs @ 1000rds a month.What about these?
From this website, it looks like I'd want the 1014:
