Mine is a little more potent than 30-06, 50% more phosphorus which is the greatest natural deficiency, at least in the south. There are a couple other good minerals out there. Just know what you need. You mostly need calcium, phosphorus, and magnesium.
Any salt based mineral will attract them, dont fall for "they hit this stuff good".
I'd love for you to try some. I'll ship you 40lbs for a reasonable price.
