If you reload or know someone who does, it's not a bad idea to make some dummy loads for testing purposes, blacken them with a marker so you know that they are not loaded rounds.
I too am in Idaho, and there has been more snow so far this year than all of last year.
By the way, whats a firing range. We don't have any nearby. Our range is a cow pasture. Makes it a little rough when it's snowing or the snow is deep :-X
