It was often done but I found that repeatable accuracy made it unnessary. While it is used for hunting the results so far have been good. I have a QD scope in my day pack should there be a shot long enough that I may be uncomfortable with the aperture. Hasn't happened yet but am prepared. For studied shots, making sure the bolt is fully turned down with the same feel each time gives good results. For hurried shots the target is obviously closer and if there is a little "bounce back" of on bolt closing, the difference in POI is so slight as to make no difference. I built my 7x57 on an almost unused 1908 DWM action, and it's tightness helps a lot. You may notice how low mine sits on the bolt head. Instead of dovetailing it to the cocking piece I had a sleave made with an off set so we could sit it as low as possible for a reasonable low sighting of the scope. It is set so that the straight bolt handle and the aperture with the stem down, just has clearance under the scope.
