Lyman Turbo Pro
Strongly recommend the Lyman Turbo Pro after reading lots of forums on the subject. We use a combination of ground shells and corn cob media - both from a large pet store supplier. Then, I recommend about one teaspoon of Flitz liquid for the shine. The pet stores have much lower prices than those products that say - reloading, on the bag! And, they are 100% natural - the real deal!
