To answer a few of the questions,
1- pistol, 1- carbine and 1-precision rifle = 3, three gun match.
After over head and ~ 18 paying participants, as a few will get comped, the Gun Club will break even. And that's only because I'm providing 95% of the steel.
Spectators are fine, there will be some vantage points for the run & gun. Any spectators must check in with me 3-4 days before the match.
Travis answered the speed limit/ magnum questions.
You don't need to be super sonic to 1760 ( 1mile), you just have to have a bullet that drops back into subsonic with out issues. There are several that will, and some that won't.
There is only the one target @ 1760, and it won't make or break you. You need to have a well rounded precision rifle set up.
Hope to see you all there!
