8point. TR now has two sizes. 12 an 20 lb each of which actually will have an extra 2-5 lbs over the labelled weight. Could not keep up with demand with just the one size (16) . Deer will use the man made loose mineral if there is nothing else available. The loose will dissolve into the ground faster in the rain an force your animals to eat the dirt , which they don,t need in their diet. If you are set on using a loose , TR will have one on the market in the very near future, and at a more economical price than the rock itself!Hhope this helps.
