I have the M6 in stainless 22 Hornet / 410. I've shot it quite a bit and think it's a very versatile firearm. I chose the 22 Hornet over the 22 LR thinking that the Hornet could possibly take a deer (closer range - up to 100 yards). I'm trying different rounds to determine what shoots best for my M6. I'm trying slug and buckshot loads in the 410. There used to be a manufacturer of 410 flare loads but my understanding is that they are no longer in business (if anyone knows different I'd like to hear from you).
I look at the M6 as strictly a food gathering type survival firearm. The stock has places for extra rounds and the whole thing breaks down into a small size. Springfield makes a case for a broken down M6. The pin holding it together can be lost but other web forums suggest a number of fixes for that problem.
I'd like to try an AR-7 and have looked at the Henry's model. I'm still not sure about the durability of the AR-7's I have seen - they all look pretty flimsy to me. Anyone have better information on these?
As far as protection from the two-legged variety of critters, after finding three meth lab dumps out in the woods this week (and it's only Wednesday for crying out loud!) I'm giving that more serious thought.
