Zan slug expansion

First one I have recovered from a small furry critter. Squirrel at 35 yards facing me with his head down, shot went thru the spine right at the base of the neck and tried to exit thru one of his rear legs. The thigh bone in his rear leg was jelly and the slug stopped in the skin. These are the 25.5gr and pushing 950 FPS. Great expansion for these slugs (but crappy pics). Measured .347 at widest point on the recovered slug.

Are these .22 or .25 caliber slugs? Which platform were they shot from?
 
Two recovered in a week! This one gave me the reverse angle and mister squirrel ended up taking a 50FPE enema. This one went in the backside and I recovered it from his front shoulder in the skin. The expansion was not quite as round as the previous, but man do these things open up. Link to this one below as well. In case you are wondering why the follow up shot.....well I do that quite a bit for research purposes and for checking to make sure my scope is right. I noticed yesterday that my POI was off by about half an inch and realized I did that from the way I transported the rifle from the range this week.

Finally was able to get out for a couple hours to play with the tuner. 50 degrees and a wind that shifted from the left to in my face made things a bit challenging, but was able to find some decent results anyway. This was where I settled on the tuner with the same Zan's at 100 yards. 4 of them at .75" with that pesky 5th straying out to 1.5". I am ok with this as I know my hold is not as consistent as the real shooters. This kind of expansion AND shooting well at 100 yards is why I love these slugs.
