I broke one today, more or less purposely. It had lifted a sliver where the grain went around a small knot. (Osage, BTW;) I just decided to shoot it till it broke. It was shooting nicely, then came the tick. On the next shot I released quickly to the tune of another tick. Third shot it blew.
For the record, like the few other bows I have had break at full draw, all the pieces when toward the target--away from me--except the handle and lower limb, which just stayed in my hand.
