I really don't remember. I've killed 5 on a stand by myself, two different times. Pretty sure there were 6 came in on both of those, with one getting away each time. Might have been more than one get away on one of them though.
Have had at least five stands this winter, with 4 or more called in. There were 6 called in on two of those (one of them might even have been 7, I think).
Have had four stands this winter with 3 or more killed.
Most ever though, heck, I can't remember. Would guess somewhere around 8 to 10 probably.
