Jim you might want to give these guys a call.
http://www.g2gtactical.com/aboutus.sc I was in there yesterday picking up 1 more lower before the changes next month, and Tim was telling me he was now offering some frangible ammo at a reasonable price, somewhere around $300 per 1000. I don't know exactly what ammo he has to sell or if it is even legal to hunt with where you are, but the frangible I have immediately turns groundhogs, skunks and other critters to a bright pink mist without so much worry of ricochet and is designed for use in an AR15/M16.
Be interesting to see how the V-max works for you. Some love them out of their AR and others, not so much. Just got some Varmint Nightmare from Midsouth that I want to try since the latest AR is going to have a custom 24" stainless 5 flute barrel and be set up to reach as far as possible.
BTW Tim and Corky are both great to deal with.
