If the keeper's sling you're referring to is the one with a leather loop on each end, I have a definite opinion about them for turkey hunting. Last Spring, I used one I have to tote a heavy Ithaca NID. I set up on the edge of a pasture and called up a gobbler. The bird spooked for some reason and ran off. After an appropriate period of mourning, I re-slung the gun and got up to move to another place. When I stood, the longbeard was in range down the field edge from me. He didn't see me at first and I tried to aim, but the sling loop over the barrels prevented any site picture. I tried to remove the loop, but couldn't do it in my panic. The bird flew and I took a shot ignoring the sling and the invisible front bead. I missed and blame the sling...Geo
