Tests were conducted at the Linebaugh Seminar in Cody, Wy June 2002, 2003, 2004. Two bullets were fired, one into stacks of wet paper, and another into a 4" dia. beef knuckle joint bone backed by wet paper. Loads with n/a in the paper or paper & bone columns were not fired into that media.

I'd like to thank John Linebaugh for hosting the seminar and orgainizing the tests, and the record keepers who tracked all the loads.
