Open ammo bag
This lightweight and sturdy canvas bag is strapped to the belt. You have ammonia in the inner compartment and empty sockets in the outer compartment.
Highly recommended for hunting ducks and field birds where the birds sometimes come close together. You don't have to open a lid and can reload faster. Place with two boxes of ammo in the inner compartment and just as much empty sleeves in the outer for the slider.
The pockets are deep and as long as you sit or stand up, the cartridges are guaranteed to remain.
