Best range for you guys in SW IA is High Lakes Sportsman's Club outside of Afton Ia. It's about an hour SW of DSM (East of Creston). Find them on Facebook. Berms with steel out to 770. They host a few club matches, one or two border wars matches every year and just held their 1st 22 match. Great core group of guys that run their matches and the yearly range membership fee is less than a couple cases of quality beer
