Two and then I quit the game of bow hunting, because I would rather hunt rifle season. And I could have killed them with a rifle and it would have been easier. What is your point?
I certainly have killed at least 60 plus Deer with a fixed 6x. And more with 4x our 3x. And most have been under 50 yards. It's not that hard.
Anyway, I've posted these previously..
Leupold 6x...Around an 8 pound Model 70. The Deer was on a serious run after being bounced. Around 30 yards.
Leupold 6x at 3 big steps max....Kimber Montana
Leupold 1.5-5x....Set on 5x...McMillan stocked Pre 60 70....Bounced out of its bed. It made the mistake of stopping to look back. 80 yards +/-
Before you start calling me out, perhaps you should come up with something other than talk.
It may not be that hard but it certainly isn't optimum or neccesary either. I know a lot of very successful trackers and still hunters here. Haven't known one who used or advocated for the use of a 6x scope. I killed my first buck and several thereafter with a .22 rifle. That doesn't mean it's a good choice or even close to optimum but it wasn't very hard either.
