Yes, I tried it. Only had about 120k DPS with sharpshooter and waited for my crit chance to hit 100% first. Went up to the first white mob I saw and used loaded for bear on it, which dealt around 300k damage to each enemy.
When I saw how much it took off their health bars (aka not a lot), I chickened out, ran back to the waypoint, left the game and bumped MP back down to 3. X_x
