West Michigan. Well, I just shot a 200 yd NRA highpower this morning in Kalamazoo. My daughter shot with me, bypassing the IDPA match that was going on in Dorr. Yesterday some of my buddies went down to Fort Wayne for a CMP Springfield and Garand match. I'll be shooting a CMP match in Kalamazoo and another in Muskegon in September. Kalamazoo Rod and Gun shoots Action Pistol every Thurday night. Southern Michigan shoots steel plates just about every week.
Whereabouts in West Michigan and what are you looking to shoot? Rifle (service, vintage, match)? Pistol (USPSA, IPSC, Bullseye) ? Trap (5 stand, skeet, Sporting Clays)? It's all here.
I'm near Kalamazoo and I can shoot some sort of match, from friendly to serious national competition, within a reasonable driving distance pretty much every week all summer long.
Here's some clubs with pretty full event calendars:
There are more, these are just the ones where I usually shoot.
