Well yaw's got me all messed up now. I've got to figure out how to start whupping bullet's. How yaw catch them little booger's coming out the barrel so fast to whup em. Seriously though I've read varmital's thesis on barrel whup, does make sense to me. If all handloader's are like me your still trying to shoot the same hole. I'm still trying to catch them booger's though ;D
