Sir - you shot 'metallic silhouettes', a game that began in Mexico with live targets [Silhouetttas Metallicas], but was toned-down for the squeamish in North America about 40 years ago. Sadly, this game is not permitted in UK, except if the targets are paper, but the fun is the same. That is the reason why the names of all the target is in Spanish, BTW - ie. borrego = ram.

Lots of luck!
