The explosive version of this groundbait is highly active thanks to its high crushed and grilled hemp content. It's designed to explode out of the feeder and release your feed quickly which is just what you want on those days when the fish are really having it. The Specimen version is brown in colour and contains plenty of crushed pellet as well as some other large particles. It's brilliant for plugging open-ended feeders and holding large quantities of loosefeed firmly in place.
