Not sure what they would do but I don't think they will shoot as well as a normal one would. I picked up around 5 boxes and found one shell that did the same. When I opened it there was no resin or buffer, just shot and wad. It seems they missed pouring the resin in that shell. Basically, you are shooting Super X high brass shot (with no buffer). Still, it will probably kill out to 40. Definitely use it as a backup shot or not at all unless hunting timber.
