I just found this thread today, being relatively new here.
In May, the 4th Annual John Linebaugh Big Bore Seminar will be coming to Carthage, Illinois. At this, we shoot various calibers and loads into wet paper and bone and examine the effects on both, as well as penetration, deformation of the bullet and chronograph the loads as well. We have not had any black powder guns show up (rifles can be brought in to test, too)
yet, but now, after reading this thread, I might bring my .44, .36 and .31 (pipsqueak) to try out for the fun of it.
More information about the meet can be found at
http://www.carthagegunclub.com/ , and I see we need to redo the dates.
It is going to be in May, anybody interested can PM me here.
The Doc is out now.
