I'm shopping for a shooting sling for my Marlin 980S .22 rifle. I'm looking for the type that loops under your shoulder to stabilize the rifle (i.e. not just a carrying strap). I just want to be sure I get one that will work with the 980. Not sure if a Ching sling is the way to go, or something else, so any recommendations would be appreciated. Don't have any preferences between leather/nylon.
