I ran about 40 of them across the chrono a week ago. I was using mixed range pick up brass, 147 grn Acme FP, 2.9 grns of SP loaded to 1.085 (more or less) at 885-910fps. I was shooting them out of a G22C with a Lone Wolf 5" 9mm conversion barrel. I think TG is a buck so cheaper than SP but I haven't done a cost per round comparison for equivalent power factor loads.
