I got a Mercury MKII in .22 for Christmas the I was 14.
A mate got a Relum Tornado and invited me over to shoot at his.
A trench filled with water, cans with holes taped up. He was made up with his relum putting holes in the cans, then I tried with the Mecury. It was blowing the cans out of the water.

Still got it 41 years later.
