I live in Oklahoma. My residence is currently in Glenpool. I realize that there are restrictions on the discharge of my firearms within city limits. I am also aware that landowners outside city limits (outside incorporated areas?) are sometimes allowed to shoot on their private property. What requirements must be met to allow non-self-defense discharge of firearms (practice shooting) on private property? Is the restriction simply owning enough land (i.e. 10-15 acres)? Is there any regulation defining private shooting range requirements (size of backstop, access limitation, etc.)?
