Downrange DR16 wads look like WAA16, but different color. The gas seal is for straight-walled hulls, if I recall. Available 16 gauge hulls tend to be straight-walled, probably a good decision by DR.

They must have come along in 2009, based on these 16 gauge group posts http://www.16ga.com/forum/viewtopic...amp;sid=db9d40bfb032f55c610d682b425d638f .
