Hmmm. Out of about 9 different types of ammo, the M22 was the ONLY one that caused problems in my TT Olympias. I had both failure to feed and failure to eject, including one partial feed that required me to take the gun apart in order to pry the round out of the chamber. This was in BOTH of my TT Olympias!
Even the crappy Federal Champion cycled flawlessly in those pistols.
I haven't tried it yet in my Marlin 795. Hopefully it will work there, or I will have nearly 1000 rounds of useless ammo.
PS: ammo I tested in the Olympias: Federal Champion, Win Super X, American Eagle Red Box, CCI Mini Mag, Remington Cyclone, CCI Stinger, Remington Yellow Jacket, Win "Golden Bullet", and the yucky M22. Most were hollow point (except the M22).
