Hard to say. But depending on the weight and velocity of the shot I'd say certainly. If you could find 1 1/8 oz of 4's at about 1200 fps, I'd say yes. Haven't bought any 12 ga shells in a lot of years but at one time that was all I shot. I loaded my own with a Lee Load all, about $50. You might get some target loads and let him get used to the thing a while first.
There are times when the deer are simply not moving and you're forced to make something happen. Maybe you're up against a full moon or hot weather. This is when a silent drive to force deer to move should be considered.
By silent drive, you're not yelling and making a commotion to scare the deer. When deer are panicked, they're liable to bust out of the cover on a dead run, and any shot you get will be tough to make.
A silent drive is different. It means playing the wind to carry the driver's...
