I done a little checking around and found the company that makes/sells the corncob media that Lyman and who knows who else uses. The lady told me that they sell 70 tons to Remington, Olin (Winchester) and Sierra. They also sell over 100 tons to Lyman for polishing media!!! Thats alot of material. She told me that I can buy it in 50lb bags, by the ton for $21. That is either #1 or #3 size. #1 being the more course as our regular stuff and #3 being used to polish bullets, REALLY FINE stuff, like walnut hull or finer. She is 3hrs away. I found it in St. Louis for $24 per bag per ton or $35 per bag individually. The rice is going to get a spin and see how it works out. I then may talk a few of my loading croanies into us getting a few bags of each and splitting it up into 5 gal buckets. The company that manufactors it is called Mt. Pulaski in Mt. Pulaski, Il and the place that is a distr. for them in STL is called Mayvalle Ind.
