You won't be saving much fur with those vmax, or you'll be doing a lot of sewing... I live in northern Vermont too and even the bigger dogs take it hard with the vmax, even in .223.
Hit one 38 pounder last winter with a 60 grain vmax (.223) and there was no saving the pelt. Good news is there aren't any "runners" or "spinners".
