I was talking to one of my Archery club members about shooting buckshot at coyotes. Since i pour my own he suggested "buffering" the buckshot. He said that many people just used crushed corn cob and packed it in around each level of buckshot pellets. It apparently helps hold the pattern tighter for longer shots, by reducing pellet spin. My question is have anyone tried this? What materials did you use? What worked best for buckshot? and what was the most cost effective way to improve longer distances? Corn bob was suggested because its cheap, light and readily availabe, i belive as a polishing agent for shells...
