slingshots are illegal in norway, but not if you make them yourself. making your own is a lot better anyway, you get exactly what you want and a lot of fun in the process.
latex tubes are my rubber of choice. they just suit me and it doesn't hurt that they last a lot longer than say theraband.
most of my slingshots are "through the fork", other types are specified.
8 mm steel BBs are my ammo of choice, but i also shoot dried peas, 4.5 mm BBs, 6 mm plastic balls (airsoft) and the occasional 10 or 12 mm steel BB.
if not specified the slingshots shown are my own design.
ps. i only do target shooting, drones showing up outside my windows included.
