First, general thoughts on the design? As with the Keiths, my interest in Mr. Sharps' bullet is part practical, part historical.
Second, is anyone, other than the troubled Ballisti-cast, making a clone? Tom doesn't appear to have it on roster (yet), and I haven't been following Swede long enough to see if it's one he keeps in the rotation.
No sense stirring the pot for a group buy if it's available or pops up regularly.
