Jeff. the reamer is headed back to me and about due to get here. Just email me or PM your snail mail address if you want it.
I'll shove some sample cast bullets in the box when I send it. The short version is that plain base cast bullets are limited to about 1400 fps in Handi barrels and gas checked are good to about 2000 fps. They have to be oversized, at least .358 and .359 is better in most rifles.
I put several hundred cast bullets through my barrel between cleanings. You can lead one really fast if the bullets are undersized or the wrong hardness for the speed, but a good load will shoot just short of forever with no leading.
Do some reading of the old threads while you're waiting and I'll try to answer any questions you still have.
