The guys over at Winchester sent us this slow motion video of their new Long Beard XR turkey load. The load features a resin called Shot-Lok that fills in the gaps between the pellets and binds them in the wad. Immediately after the shell ignites, the resin fractures and turns to powder. This process creates a tighter shooting shotshell and more pellets on target, according to Winchester.
At about the 15-second mark you can see the pellets flying out of the muzzle in a tight little group. At this point, the resin has already fractured.
