I am sorry you took it that way, because that was not the way I meant it. I was just relating my experiences and there are lots of variables that would have an impact.
I have had them run off when shot with a 22 magnum, 40g Win HP when shot at distances of 65-85 yards when they were hit in the back of the lungs, they died shortly there after. Animals can vary in their stamina especially with size and how pumped up they are. I killed a lot of coyotes with a Ruger 22 mag all weather skeleton stock rifle in AZ while hunting off of gaited horses. Usually, a hit right on the back edge of the shoulder will put them down hard, but you rarely ever get perfect shots when they are coming in to a call. I had to shoot quite a few more than once, especially between 100-125 yards which would indicate a hit behind the diaphragm and they were moving(running away, circling fast indicating that they were just checking things out).
When I moved to Az, I started off hunting around those new subdivisions off horse back, and used a custom Ruger 10/22 loaded with cci mini mag HP, and distances were close as this was thicker dessert terrain with shots usually 30 yards or closer. There was a NOTICABLE difference in killing ability of the cci mini mag with a MV of 1270 fps and the sub sonic stuff at 1030 fps. I started having longer shots, thus went to the 22 Magnum which I dearly love. That Ruger is so accurate, that I could connect very reliably out to 150 but they would run off all most all of the time at that distance. I was trying to use a rifle with less report within closer proximity of the housing so as not to upset the residents, and I hated to waste a Deputy's time when they got a call to come and check on "shots fired".
I think to get an accurate picture, you have to kill 50 coyotes or so to gauge the reactions over a larger sample as perhaps 10% will have very strange reactions to very good hits. IN any case, if you hit one in the lungs, he will usually die within 150 yards.
Later on, I went to a 17 Ackley hornet(20g Berger MEF at 3550), shot 4 coyotes in one morning, only found one of them and he ran about 110 yards. All of the shots were close in and they never acted like they had ever been hit. I went to a 22 K Hornet on that same Ruger action, that was THE END to the running coyotes shot in front of the diaphram, 40g Speer spire point(~3000fps) will shoot through shoulders, max load of H110. A best friend just had to buy that Ruger with both barrels. I replaced it with a Remington package rifle 223 from wal mart and duplicated that K hornet load with 12g of Blue dot and the 40g Speer spire point.
The sub sonic stuff I was shooting in the 22RF was 1030 fps out of my 20" bbl, and shots were 35-40 yards on an average, not all ran off, but(70%) the vast majority did, how far varied from 10 yards to 40 yards and some just were never found till the buzzards started circling. Ammo, individual barrels, distances, age and size of coyotes vary a lot.
One major issue with sub sonic ammo is the amount of antimony or Tin that is in the mix of the bullet, if any. A soft bullet that is pure lead will expand and the harder alloy bullets will not. This one thing may explain why the Aguila sub sonic ammo kills much better than the cci sub sonic, and this would be a huge factor.
After I sold the 17 Ackley hornet/22 K Hornet to my friend, he started using 25g Hornady HP in the 17 Ackley hornet, and he started killing coyotes with the rifle with out run offs, hot load of N120. Some little minor details can sure change the results.
