That's why I have my 12/12/9,3X74R drilling...with two barrels of buck shot...or the 12/12/30-06, for that matter.

Moose look slow, by the way, but they can move right through willows like they aren't there.

I don't think there is anything much quicker than a Leopard's swipe.

Also, I see no lack of speed if using a BAR in getting a second, third or fourth shot off, and indeed, with the less sharp recoil, it may be faster to re-acquire a target.
