Hi guys, bit of an odd question maybe. I work with young people and over the last few years have developed a filedsports project and cover things from fishing to air rifle shooting and conservation. What I am thinking about doing is getting together a collection of bullets to show to the older youngsters we work with, and explain what they would be used for. Only for the people that complete our recognised Bisley Course. Would it be legal for me to own just bullet heads and casings without powder and primers to show to to the kids? Any info would be much appreciated. Thanks, tim.
