Perro Del Diablo Posted September 18, 2021 Share Posted September 18, 2021 I mostly use corn cob media but considering getting some walnut. Do any of you know what size to use? I have 3 options from grainger and they are measured in microns with a range. 420-820, 820-1600 and 1600-2300. I do know the lower numbers in this scale are the finer and larger numbers are coarser. I may use for cleaning brass and also some sandblasting duties. Link to comment Share on other sites More sharing options...
Cypress Sun Posted September 18, 2021 Share Posted September 18, 2021 I use the walnut lizard litter (bedding) from Petsmart. Went out and looked at the package for a size but there wasn't any listed. If you have a Petsmart, Petco, etc., near you, you might want to check them out. it's in with the reptile items. No shipping that way. Link to comment Share on other sites More sharing options...
Capt. James H. Callahan Posted September 18, 2021 Share Posted September 18, 2021 Hmm. That's about all I've ever used as it lasts longer than corn cob. Never saw different sizes! JHC Link to comment Share on other sites More sharing options...
Perro Del Diablo Posted September 18, 2021 Author Share Posted September 18, 2021 $20 for 8 lbs petco + tax, $60 for 50 lbs grainger shipped to my door. I plan also use for sandblasting painted surfaces. Link to comment Share on other sites More sharing options...
Cypress Sun Posted September 18, 2021 Share Posted September 18, 2021 Hell, the rats would eat it before I could use 50 lbs. Maybe they'd leave it alone if I stored it in my Rugged Gear Cart. $60 shipped is a great price though. Link to comment Share on other sites More sharing options...
G W Wade Posted September 18, 2021 Share Posted September 18, 2021 Walnut hulls clean faster than corn cob, but corn cob gives the shiny finish so of you like. Only advice I can give is to get a size that is bigger or smaller than the flash hole in your cases. All I want is clean cases not brilliant shiny ones.
