There are many like it but this one is mine. This system has been causing great distress to the hog population on our place. The t-50 is a fine choice for shots 50 yards out to 300 or so but if you want to kill them all then the ATN Thor 2 with no magnification on the bennelli is the way I like to go...if I can close the distance to under 50 I can kill them until I run out of ammo
