The TAB GEAR SAC addresses the issues that you have to deal with when carrying a lot of ammo.
The SAC will hold 100 rounds of .308 ammo. It also has ammo loops on the outside that will hold 10 rounds for quick access. There is a divider inside that allows the shooter to easily segregate live rounds from fired brass.
It is very easy to store fired brass, no more trying to insert them back into shell loops or throwing them into a pack pouch to dig out later. Simply throw the empty brass into the inside compartment of the SAC and they are ready to dump out later.
I used to carry a 100rd box in my pack to matches which caused unnecessary bulk. I was looking at some more expensive ammo wallets, then I stumbled across the TAB SAC. It holds 100rds of loaded ammo easily, has a divider for fired cases, and drastically reduces the bulk in my pack! Extremely well built and priced right!
