My gut feeling is that the kind of support provided by sling tension round the forearm will be OK, it's a different thing from resting on a hard surface. I quite often find, when shooting my Osprey with diopter sights, that my groups start to open up because I'm not concentrating and holding the gun too loosely. Tightening my hold by forcing the stock into my armpit improves things no end.
