Firearms training - how often do you practice?

You need to do this or roll clays across the ground, Teaches one to lead their shot so to speak!

 

Actually i was thinking rolling a junk 55 gallon drum down a hill ,as unpredictable as it can be , animals can have the same action leaping and dodging, and changing direction .

 

Use an old tire? No rim,I would tape a target in the middle, Nothing like a fun challenge!
