Weapon-Clear Advantage Over Snail Traps
Snail Traps Are Unsafe with Steel Cored Rounds
Snail traps such as those sold by Savage Range Systems are indeed a interesting solution to decelerating a bullet , however by the nature of their construction and design they cannot deal with steel cored or indeed Ap or Api rounds.
Therefore in a LE or Military Situation where steel cored (SS109) or indeed Ap and Api maybe present Snail traps are inherently unsafe.

Snail Traps Limits on Caliber
Another safety concern is by their very nature Snail type unloading devices have a velocity and a ft/lbs limit.
Due to this the situation could arise where a round in excess of the maximum caliber could be discharged , with potentially lethal consequences.
