Good friend (passed away recently RIP) used to buy bulk reptile terrarium crushed walnut and swore by it as a cheap source of tumbler media.
He gave my uncle a bag of it and we tried it out for a while (still in the tumbler actually). It does work good for polishing the brass but we found that it kind of stuck to the inside of the casings and you had to tap and brush them all out before resizing, etc.
Before we toss the stuff, is there anything we could put into the bare walnut to make it not stick to the casings and be more effective?
