shaman,

A description of the "slap" method is included in the "Shoot 'Em Again" chapter in GUN GACK II. I have described it elsewhere, but that's probably the most available source.

Would also like to comment that it is very possible to jam a typical Mauser-extractor CRF action by short-stroking, contrary to what some shooters believe.
