What a coincidence, I was going to post something similar in reference to the super glides and loading. I noticed sometimes when I load them, they are loose and seem to "jump" the rifling when going down. It seems to me that when I use the black sabotS/W it is tight to load and seems to engage the rifling and twist when being pushed down. However, usually when I load a super glide S/W it feels like it has the rifling for a bit then seems to slip a few inches and catch it again and so forth until it is seated. Sabots do twist when being loaded don't they? It seems to me that if they "jump" when loaded, wouldn't they do the same when shot therefore makingthem somewhat erratic?
