Well, probably fair to say the pure bison were "unruly" and not very "trainable", but not dangerous as in charging people or whatever.
The two small beefalo herds I observed way back when might have been a bit more skittish overall, but not much, you could walk right up to them like normal dairy cows, and that was before the strains became more standard. Nobody starts with pure bull or cow bison anymore, and I'd wager the current strains behave pretty much the same as any domestic stock.
But on topic to my original comment, it think it's safe to opine that a few scattered around Ted's 300 acres would pose zero risk to a hunter, even if they were pure bison, which seems extremely unlikely. More like shooting a Holstein in a pasture rather than a Cape buffalo in the bush.
