Kent's proprietary, high density 9.6g/cc Bismuth is a premium non-toxic load that will be sure to cancel all flights this waterfowl season. The highly uniform pellets are as soft as lead for maximum energy transfer, delivering bone-crushing patterns at greater distances, and less wind resistance on windy days. Kent's high-performance base wad was designed specifically for semi-automatic firearms, to ensure smooth and reliable functioning, shot after shot.
