Basically, this action is too long for the 222. The magazine won't support the cartridge long enough to ensure alignment. Said another way, the cartridge is still too far from the chamber by the time it leaves the magazine to ensure chambering. It's a long action rifle made for a short action cartridge with a sheitty magazine design.
That's what I was thinking when I read your OP.
Is it a Tikka length action or just a .308 sized cartridge type action?
