"shoots five into one ragged hole" (I guess as opposed to one clean cut hole)

"can cover three with a dime" (I don't have any dimes...spent them all on bullets and powder)

"all day" (meaning of course the gun in question can shoot accordingly 'all day') not just part of the day.

"tactical" (which at one time meant somehow connected to the military but now means anything black)

"there are no dumb questions" (apparently the originator of this little quip never read all the questions)
