I just carried a Win. M-70 Coyote rifle with a Nikon Tactical in Badgers for a couple of days of chasing coyotes in SW Sask. The sling was a Vero Vellini that I recently bought, and it is an impressive unit. I have never used a stretchy sling with a relatively heavy rifle, the stretch really makes carrying more comfortable. This sling does not crawl off your shoulder, nor does it move much at all as you walk or bend-over etc. I did not have to push it back onto my shoulder or re-adjust its positioning like I do with ordinay slings. You can feel the sling taking up the weight of the rifle on occasion as you step down off a rock or something like that. Makes carrying the 10-11 pound rifle much more comfortable than with a standard nylon or leather sling. Somewhat expensive for what you get, but a very good hunting sling.
