Upper nisqually sportsman's club has a 550 yard range open any time ther is not a match, but you have to be a member, or guest of a member. They also have para tidal/ precision rifle matches on the first Saturday of each month where they shoot primarily steel from field type positions like barricades, rooftops, platforms, parapets, tank traps, and whatever other things they can think of. They vary positions, and no two matches are the same. Know your dope out to 600 yards and it is lots of fun.
Entry fee is $20, you do not need to be a member to shoot matches. No magnums, no bullets with any ferrous content...check your bullets with a magnet. They have managed to keep the matches fun, low key, and friendly so far. Most shooters there are happy to help new people out.
