Jack Hargreaves got me interested in airgunning.

It was on the 'How' childrens' program that he showed how sand is an effective backstop. He used a break barrel pistol and I remember him showing the placing of the 'slug' as he called it into the back of the barrel prior to the demonstration. In those days I suppose that would have been an appropriate moniker.

Odd what stick in your mind from being 8 innit?

On the other hand a slug would have made it an early form of paint-ball gun.
