Ground hog shrugs off jsb 18.59 gr .22 headshot

I have taken many groundhogs with the 18gr JSB's, but it is all about shot placement. A heart lung shot will equal a GH that goes off and dies in the hole, and if others live in same hole, it may feel like you didn't finish him off. A shot to the area between eye and ear will normally drop them instantly.

Do you have a chrony? I was hunting birds one time with a springer and didn't know that I had a seal blown so all it would do is knock feathers off and hurt them. I would suggest running it over the chrony just to make sure shes running with all 8 cylinders. There is a certain part of a gh skull that is really tough tho. Imagine if it was human the top of the forehead where the hairline is. That area is thicker and rounded so it could help to deflect. Good luck but if I were you I would want at least 15 fpe behind that pill when it hits the gh. I have never seen one shrug off that kind of power with a head shot. In any case I dont think hes laughing. 
 
Ive sent them damn things to orbit with 6mm ackleys and they still got to their hole! If deer were that tough we would need rpg’s lol. I hit one lookin right at me between the eyes with a 22’lr and it ricocheted’ and he took off. Those things can be tough!

When I doubt go big, I use to coyote hunt with a 300wsm.

Thats what I like to hear!
 
Ok I usually aim between the eyes it's like a 30 yard shot so I figured headshot would take him out didn't think shot placement would be an issue also I use a vortex amg hu1 holographic sight so aiming for a specific head shot is ify its basically aim for the head or aim for the body works great for squirrels but I don't want them running off mortally wounded and suffering for hours you think the heavier pellet will put him down DRT or do you need a specific shot placement regardless of fpe the 29gr piledriver is chronied @ 749
 
There are almost endless variables when shooting critters. I like to Google Image the skulls of animals in question. It usually sheds light on not only placement but the proper angles to shoot them.

It's like when you hear people talk about bullets skipping off bear skulls. It's not that they have super thick/hard skulls as much as it is the shallow angle of them when facing you.
 
The military developed sloped armour for tank frontal glacis plates for two reasons. It increases both the likelihood of projectiles glancing off the glacis and the apparent thickness the projectile needs to penetrate the armour. 

The front of a Chucks skull is similarly sloped and armoured. If given the choice, I prefer the side profile shot between eye and ear.

Exactly.
