I decided to take a few pictures of one the CCI Gamepoints I recovered. I did not recover one of them. Sorry for the bad quality.
Here you can see the nose of the bullet did not expand.
It simply acted like and FMJ, although there was damage in the gelatin was somewhat impressive (somewhat like a 5.7x28mm), I was hoping to get an expanding projectile and 12-16 inches of penetration which is generally what I get with the JHPs I have tested.
This is the side of the bullet that stuck the cinderblock.
As you can see, it still had plenty of power in it, even after traveling through 16 inches of gelatin. I would guess total penetration with something like this would be around 25 inches of so. [For what its worth, I tested the CCI 40 grain Gold Dot and it exploded when it hit the gelatin. IIRC I got about 10 inches of penetration from the largest fragment. I reminded me of a half scale 60 grain .223 Ballistic tip if that makes and sense. It was certainly one of the best .22 Magnums I have ever tested. CCIs generic Maxi Mag 40 grain HP typically holds together somewhat well, expand to about .40, and penetration 11-14 inches, at least in my testing. Others may get different results, especially depending on the length of the barrel used.
