It is common enough to not bottom out on preacher curls, if not skipping them entirely due to the fear of injury. Among the very effective ways to achieve stimulus I personally find preachers to be too risky to be worth it. Laying bilateral dumbbell curls on a flat or slightly inclined bench allows you to get a very complete stretch with a substantially larger ability to safely bail.

Yeah, almost every lifter has seen that preacher curl double bicep tear. I was watching through my hands.
