After multiple years of putting the kolpin to use on rough desert roads on an atv, I don't trust the amount of vibration tranferred from a heavy rifle to the hardware which makes the case to rear rack mounting connection. Had one shear the rear quad rack straight off off which was the final straw for me.
As a kicker, hearing a rifle rattle in the case is enough to make me cringe even if I haven't experienced a POI shift. (thank solid bases and mounts).
Only using a quality hard case secured with tie downs to the front rack anymore. I second the fact that it will be wider than the machine, but I'll slap any tyle of brush except a tree trunk with the case out front before going back to a kolpin style mount.
FWIW, this is from experience logging decent mileage on rocky desert trails which may be harsher than most conditions.
