Now i am using mining laser as a ranged-weapon to kill those creepy creepers ^__^
AND, i've found out that explosive shot is useful for... Tree harvest! You can use it to blow up those huge trees, and this mode doesn't set them on fire!
also using mine to do just that 
also with normal trees, aim.... hit the top. aim...hit the top again. BOOM tree's gone.
giant rubber tree's? FIRE AT WIL 
i usualy empty the lap pack within one minute during this obscene crazy fire mode.. and usualy destroy the landscape along with the tree haha
