Favorite .177 hunting pellet?

I’m in a quandary. My most accurate and highest coefficient pellets are all 10-11 grain domed pellets. Out of my HW97K @ 14 fpe, however, they blow through birds so easily that if it doesn’t hit perfectly I will sometimes get fly offs. Especially on frontal shots. I’ve noticed that these domed pellets have zipped right through every bird I’ve shot with little discernible expansion. What’s your favorite, most accurate .177 hunting pellet?
 
Accurate shot placement is vastly more important than energy transfer so that always comes first. As a practical matter, it means a dome is the only choice for longer ranges. But for modest distances, if you can find a wadcutter that groups well, they are absolutely devastating to pest birds and squirrels and such. Hollow points seldom produce any meaningful expansion and end up being less effective...for a given shot placement, that is. Meaning if a hollow point proves sufficiently accurate to cover a greater distance than a wadcutter, by all means use it when you need to reach out a little further.

So for example the 9.3gr RWS Supermag wadcutters group well in several of my rifles out to at least 35 yards, and since a good portion of my pest control activities are done at 25-35 yards, I use them a lot. Kind of expect them to do well from a decent Lothar Walther barrel (around 12fpe):



But the more surprising thing is they group well from the OEM Chinese barrel on a QB79 HPA conversion, and at speed that is generally regarded as absurd for a wadcutter:



Either way, these things are wrecking balls when they hit a pest.

But then at a couple of locations where my shots exceed 50 yards, I'm using domed pellets 100% of the time. For that middle ground between 35-50 yards, I'll sometimes use a hollow point. But the reality is I just don't find many hollow points that really deliver both pinpoint accuracy and a useful degree of expansion, so for the most part I end up flip-flopping between wadcutters and domes.
 
You're already using the best pellets. 

There's not enough energy at play here for things to work like an expanding powder burner bullet. 

Penetration and accuracy are the only things you have on your side with air rifles. There is no "shock" or "knockdown" with these power levels. Just put it where it will do it's best work and that's it. 

There's a lot of bird that's not kill zone from the front. Just saying.
 
I have had better luck with 177 Polymags at higher speeds and longer distances compared to 177 wadcutters, although wadcutters would be my first choice in this situation if they were accurate at the distances you need them to be. I'm guessing your HW97 would sling either of them pretty fast.

@Elbowgrease has shot 177 Polymags over 1000 FPS with good accuracy up to 68 yards. Might be worth looking through his post history. 

I've never shot Hades in 177 but would want to test those as well.

Thanks! Polymags, Hades, and the RWS Supermag Wadcutters are all pellets I might look into. Any other recommendations ?

In your situation I'd also want to try things like the JSB Ultrashock & the Crow Magnums. Heavier wadcutter-like hollow points. But the three quoted above are what I'd try first.
 
First hit the killzone. If you do that all of your other problems go away. If you don't no amount of power and excessive force is going to save you every time.

I agree. Accuracy/precision, i.e. "shot placement" means more than anything else. If you are getting pass through too often, then you are using too much fps/fpe.

If you can decrease the fps/fpe and maintain accuracy/precision, problem solved.

The problem, afaik, is that it is a chore to do that with most, if not all, springers/gas piston airguns.

Just one, but not the only, reason why I went to PCP and haven't looked back.

JMHO and YMMV
