HHRP = Hidden Hills near Knaw Bone, IN, correct?
What type of format are you going to run? Rifle/pistol, rifle/shotgun, shotgun/pistol? What kind of scoring are you going to use? Hit factor? Time +? Horner? Whose rules? IMGA, USPSA, IDPA?
I'm really happy to hear of another club wanting to do multi-gun matches, and so close to central IN. Best of luck.
