Hi

When the world was young the only powerful air rifles available, if you could afford them were the Airsporter and MK3. The brochures claimed fantastic ranges and no mention was made of muzzle energy. Indeed the only way to gauge the power was to fire them against a paving slab and compare the pellet deformation. I would be interested to have the Forum opinion on there realistic power levels although I now believe the pre war B.S.A.'s were more powerful and better guns.
