I've read that the torque produced from the heavy bullets turning through the rifling is what really causes problems. Basically twists it out of your forend grip and then all he'll breaks loose. I have no actual experience nor want any. Good luck as this thing has the potential to do physical damage at 247 f/lbs and 47 fps recoil.
