The jaws do not close as tightly as the 220s is the only way I ever figured they could get out. Where I often had so many otters around that we checked traps two or more times a day we had more than a bunch in 330s still alive. In 220s they die right now.
Had a bunch of 210s a long time ago and they were not up to the task, at all, as the otters would warp them.
