Aim Surplus has Stirling 00 Buckshot. Never heard of it so I googled Stirling. Made in Turkey. Funny thing is Stirling makes Anti Drone shot shells. Specs are vague. Wonder what size shot you need to down a drone?

The drones you need to worry about can't be reached or knocked down with a buckshot load.
The ones that can, will fall to a Hevi-Shot goose or Dead Coyote load.
