I almost exclusively use #masterbuilt lump charcoal in my MB 560 gravity feed. Getting ready to do up a picanha this afternoon, and decided to clean the bin grate real good so i have a good base of lump to light. The grid would not pull out but was wedged. Reached all the way to the bottom of the bin and found this. not trying to be a whiny little b'$%ch, cause things happen. pretty good chunk of rock that came from one of my last two bags. granted MB lump is only $15 at wally world but i dfind the burn better that royal oak. except the shit that doesn't burn.
carry on.
carry on.
