Hit ratios not only vary by the shooter - but probably even more so with the same shooter in changing conditions. For me, any squirrel within 225 yards is probably going to get whacked. Stretch that out to 650+ yards on a day with 25+ mph varying wind and my hit ratio might drop 90% or more. Realistically, as I'm always testing my ability and trying to improve on the long shot - I miss a LOT. On average - I'd guess my ratio is about 30% hits. It is even less than that when I'm concentrating on the ones WAY out there. Nothing more fun than bracketing one and hitting it when holding four feet off for wind. My hit ratio also goes up when using an A/R in really windy weather due to the faster second shot.
Reading about the box of ammo for one squirrel at 983 yards, it reminds me of how I once shot something like 35 rounds at the SAME squirrel (and missed all). He was running around on the snow "way out there" and the wind was moving. I kept trying, thinking I'd throw up a bit of dark earth on the snow to mark my impact. It never happened. The squirrel finally tired. I think of that lucky sucker often.
