I shot him in the chest and the bullet blew-up on impact, with only a small chunk exiting the squirrel's back. Testing like this makes me wonder about what this bullet will do when it hits a Coyote rib, or if it clips the leg on the way into the chest.

I thought it was interesting! It sure knocked the heck out of the squirrel, sending him into a back-flip and feeling no pain!

Edit to add: My buddy who was with me just told me that he thought that the bullet may have blown up when it hit one of the GS's arms (which were in front of it).

I have no sound reasoning as to why bullets do what they do on impact. My only thought would be that it was a short shot & the bullet hadn't lost any velocity on impact. Which caused the tiny bullet to explode prematurely on bone impact. Your buddy could very well be correct in bullet placement on the arm plus the breast bone was right behind it adding more bone mass. Todays bullets are designed to be more violent inside than ever before so I can see where bone could be a problem even on small critters. I wouldn't worry about that one shot too much. But I would start trying for head shots to see if you could replicate these happenings on a more solid area of the squirrel. Which bullet were you using & what is available?

Glen...You say you have seen that with .22 WMR? Amazing Eric. Impact was devastating. Have you tried any of the HP ammo yet?

I shot a bunch of Prairie Dogs with the same round (17WSM - 20 grain V-Max - 2950fps) and had the opposite result, even on head shots. I think you guys are correct that a combination of the arm bone and the chest bone (do squirrels have a big sternum?) probably caused the bullet to blow up on the outside. The exit wound in the back also shows that a piece of something went right through?

Mike - No HP ammo available yet for the 17WSM. I haven't tried the 25 grain V-Max bullets either, so those may have different results as well.

Yeah that bullet is cookin out across the landscape & todays bullets are soooo fragile nowadays. I'm also wondering if maybe a piece of bone didn't make that exit wound. I know tree squirrels have very little for sternums but the arm added in might be the difference. It's been a long time since I seen that Mike. It was back when I had an old Chuckster. Pre Varminter.com days for me. If I remember correctly it was a CCI HP offering. Maybe a 35gr'er. Had it happen 2-3 maybe 4 times on chest shot groundhogs. Never knew why. I was just happy to see their insides on the outside. B)

Is easy to tell which one was the exit hole.
