I should have said that I have three bags of lead shot. Each bag weights 25 lbs. I keep them inside some Caldwell lead shot bags to protect the lead shot bags. The Caldwell bags have zippers on them to open up the bag so you can stuff a 25 lb bag of lead shot inside the Caldwell bag. The Caldwell bags have a carry strap sewen onto the bag. That makes it easier to pick up and carry each bag.

The Caldwell dual frame allows the AR15's magazine to fit between the two rails. Still I only use the 5 round magazines in my AR15 when sighting in my AR15's scope or my EOTech HHS II system.
