the homestead range is a free public range and I would not recommend it, unless you want to take your life in your hands..it is unsupervised and you will see all manners of shooters there..
if you are looking for permanent membership, there are 3 in the vicinity..one range is in the south east of Calgary (Calgary & District Target shooters), the Rosebud is near the homestead range in K Country and Olds has a fine range as well, Mountainview..
link is here for all
