Can't believe I found a new box of .22 Magnum. I wish someone had a 6.5" barrel for gel testing!

Sorry, can't help you there IC
My Super Single is 5.5" and the SP101 is 4.0"
Some tests are being done on YouTube in short barrels. I just don't know who really uses that with this round and the pistol rating is a 6.5" barrel.
These broke the 200 FT LB barrier and are the strongest so far. I bet these would do damage in gel or tissue and would be my #1 pick so far.
