I recall someone selling buckshot alarms once upon a time. Using a trip wire mechanism. Tempting but i'd likely shoot myself with the damn thing.
anyone been watching the walking dead??????? a big pit in your drive with zombies at the bottom, thieves fall in and zombies eat them, sorted.
also didn't someone sell mines that when activated blew paint everywhere,or if you didn't have paint but filled it with rancid shit ,well you get the idea.
Poacher Alarm - Game Bags & Accessories - Shooting - William Powell Ltd get a couple of these, then fill the empty part of the cartridge with some road salt. With a bit of thought you can rig it to go off on 'pull' or 'pressure release', the worlds your oyster.
come to think of it mate of mine years ago had an item that used shotgun cartridge blanks on a wire and pin mechanism hmmm wonder if you can still get them ?[/QUOTE] that's what I was thinking of earlier
