How clean is a clean kill?

Hi all,
Relative newbie here. I got my first half-serious air rifle last week and shot its first possum with it last night down the back of our section. First time with my own equipment, after having shot maybe a dozen or so using friends ruger 10/22's.

Last night there was a delay of probably a 10-15 seconds(?) before it dropped from the tree. So long that I was about to place a second shot by the time it did drop. I then searched for it for probably 10-15 minutes but never saw or heard anything from the possum and never did find it (though it's a very challenging bank with dense undergrowth and not even sure i'm looking in the right place)

1) What kinds of times are you typically seeing between impact and a possum dropping?
2) Is it possible I just winged it and it dropped the full 20+ meters to the ground and then hid or snuck away in near perfect silence? I would really like to think the shot went where I aimed it, and the delay was just how long it took to bleed out and lose consciousness / fall.

Targeted area: Front chest/neck, unconfirmed it actually hit here.
Ammo: Winchester domed pellets, unknown weight.
Rifle: Gamo Whisper wildcat. Stated energy 17.7 fl.lbs / 24J.
Distance - 20-25 meters? shooting at 70 degrees up.

Trying again in the same spot tonight. I really want to make sure these are clean kills, and adjust things as necessary if not.

Firstly, welcome aboard. I wouldn’t be concerned by the ten or fifteen seconds taken for it to drop. Even if your shot knocked out the animal’s central nervous system (instant death) it could still take time for it to drop if it was clinging on to the trunk or a branch of the tree. If you have zeroed the rifle then trust your shot and don’t start second guessing yourself.

It's good that you are concerned about this, every animal deserves a humane kill. Possums are harder to kill than other small game/pests in my opinion. Maybe check your zero and test fire a few shots at a similar angle.

In an ideal world, we'd aim for about zero seconds between impact and death. The means using the right tool for the job to help ensure that. It's not always going to happen though.

I have shot plenty of critters with air rifles. But after shooting possums with 22's and seeing bullets either ricochet off their heads or come to a dead stop against their skulls, I'm not sure I would want to tackle one with an air rifle. They can be tough little buggers. Dropping from a tree isn't going to put the final nail in the coffin either - they aren't that heavy and bounce quite well rather than going splat. I usually go for neck or chest shots on them with the 22 to make sure there's a soft meaty bit there to for the bullet to dump its energy into. That can result in them clinging on for a few seconds. No drama.

We have no way of knowing if you walked past your one a dozen or more times in your search any more than you do. But if it really was not there then it must have crawled (and died a somewhat slow death).

I've shot possums 6+ times with a subsonic 22 and had them hang by the tail for ages before dropping

If you miss and get it in the guts it's a distinctly different sound, the thwack sounds like it's in the bottom of a glass bottle

Some possums are very hard to kill IMO

I've shot them and never had them drop, but found them the next day cold dead still sitting on the branch. I've clean missed others that got a fright and apparently let go of the tree and fell straight out too! I know I missed, due to the chunk out of the timber the thing was sitting on. It's a relative thing, dropping isn't a sign of a kill. As far as it goes, worthwhile noting that what goes up must come down and that also includes the pellet - need to make sure of a hit on something solid when shooting up. It is a marginal example of "safe direction" at the best of times!

As far as finding it at night, in long grass under a tree it's always a hard ask. Probably still there as the last stop at the bottom never improves them.

Welcome to the forum, you'll find lots of info and helpful buggas on here.

When shooting possums you may find you'll need to aim differently than you normally would. If the possum is almost straight up it may be 10m up vertically and only 2m away horizontality so you would need to aim as if it was only 2m away. this link tells it better than I https://www.rifleshootermag.com/edit...t/83768#replay

Just remember NEVER shoot a possum directly over you, it's like a grenade with claws landing on you.

Thanks guys! TBH the noise it made did make me wonder if it'd actually hit in the belly. Firing it again this morning it may have been a bit out (though high and to the right), investigating again shortly, and have set up a camera with alerts + wire mesh for banana to install later tonight.

The 17HMR with 20gr CCI are very brutal on them.

Try cut apple with cinnamon powder

The brown V in the throat makes a fine aiming mark. Yes up to a minute to drop if chest hit,if in Doubt shoot again.

Will hang on by the tip of the tail for quite while, even with a good head shot.

I'd say it was a clean kill, the clue is in the delay (to bleed out internally from what is a pretty small wound) and the fact you didn't hear it on the ground. Wounded animals always make extra noise and possums are not real quiet even when they are trying to sneak away.

I wouldn't use an air riffle on possums, I don't think its enough gun for the job if you are after clean humane kills.

I have seen people fire numerous .22 rounds into a possum and they still don't drop so an air riffle is not a good choice, possums are tough little buggers and you need a bit of grunt to take them out cleanly.

Good luck with your shooting.

He's in Pomgolia - they're not allowed points on their knives over there

Hi quiet whisper, welcome to the forum, it's great to see your excited about getting into hunting and have a great attitude in regards to quick clean kills, possums however are very tough little critters, I've had them hang dead in the tree by their tail for over 10mins, got sick of waiting and shot it's tail off to get it to drop, it was stone dead when I picked it up. I've had very little experience with air rifles, my trusty Ruger 10/22 is my go to possum, rabbit and hare shooting rifle, maybe you could try a pointed hunting specific pellet? Hopefully someone with more air rifle experience can give you some better advice.

I have a .22 air rifle which has accounted for many a possum in the willows at our place.
You'll want to get a few different pellets and see which are consistently accurate in your gun. I have decent luck with the JSB brand but your mileage may vary.
Get some pellets that are a bit heavier, 18-25 grain, the light ones are useless for tree bears.
I find the best option with the air rifle is to aim for the head and keep shooting, if it gets hung up on the tail shoot it in the head again, it makes them spasm and fall out if you're lucky.
I always move closer as I go so when they fall you can finish them off quickly if need be.
Good luck and with the air rifle practice makes perfect regarding accuracy, you'll find the way you breathe and hold the gun is very important to be consistent.
