If you can get them to group well, try the Crosman 10.5 Piranha pellets. Unfortunately, so far, in my Fortitude shooting at ~755fps, they don't group as well as the CPUM.
However, it is the ONLY "hollow point" Crosman offers in 10.5/.177
I may have to give them another try as I haven't tried them since I figured out and fixed some of the problems with the Fortitude.
Thanks for posting the video!
