I was thinking of the Accelerator loads as well. I don't think tracing had very much to do with it being discontinued. It was never a good seller and accuracy suffered horribly from the sabots. If I was going to use my .30-30 in this manner, I would carry some of the 125gr and plan on head shots. Yep, too much gun, but I don't reload anymore. Even when I did, I would stick with published loads. I am fearful of lodging a bullet somewhere in the bore and not realizing it. Almost happened once with a smokepole I had.
