Similar in concept but for a different purpose 12 bore birdscaring cartidges are still made.

They are made to be used at airfields in unchoked shotguns or in sleeved signal pistols.

“The cartridge fires a sub-calibre projectile with delays from 1.3 to 4.0 seconds to give varying ranges. A loud report or continuous screech is given at the designated range. Range distances vary from 40m to 90m dependent on angle of fire and weather conditions.”
