Now I just have to figure where I seen it. Glad someone remembers with me.Same here. Groups tightened up noticably without crimps.
I recall reading about crimps and the potential effects in Speer literature as well. However, a quick look at the Speer #12 manual shows all the bullets listed for the 30-30 with cannelures. That being the case, I'd give them a light crimp.
