Thanks gents! I have some Hades incoming but will also go for the ear shot going forward. As @L.Leon said, they could’ve expired in seconds after being hit as I can watch the impact through the scope. It’s just that I’m not 100% sure because they dive into their hole.
Appreciate the discussion.
IMO, with a good placed head shot, 30fpe is more than enough. Similar weight, quality pellet brand types really doesn't matter as long as they're pinpoint accurate in your gun. I've taken out chucks at 25 yards or more with cheap domed Crosman pellets 22 @24fpe 14.3 grain pellets.
If you get a real head shot in, there is no diving into the hole. After a head shot small fur bearers can't lift their head they are brain dead with only the spine sending signals to kick uncontrollably for a few seconds, mostly back legs. Actually, if any small fur bearer lifts its head even a little after you shoot it, thats a good way to know they are just wounded and need a second.
No way after a devastating head/brain shot can a critter find his way back to his burrow. Might fall in it unintentionally after kicking around if its close within a few feet. But doubt that could happen twice as it did to you. Nope you missed, it happens to all of us at some point.
Thats why for pest removal I like to bait them so they stay put eating and you can observe their feeding rhythm then take your time knowing they won't be moving their head for a few seconds.. Because thats all it takes is little head movement to make a graze or miss. IMO baiting for pests its the humane way to go...
Baiting for chucks works good, because many times they stand right up giving you a great target like below... Cantaloupe in front of a backstop at your perfect spot. Your misses will be far and few between.
