I had a bunch of pop bags, good stuff, but hard to handle. The leadwakes bags are lead, so denser, pop bags was not lead, it was steel shot. The handle on the pop bags is like on the side. Its like grabbing a small grocery bag, and when when you lay it down, you have to lay it on its side, doing this with a bunch of bags when changing sides is a pain. The leadwakes bag, the strap on top. so you lift move and set. SO much easier. The leadwakes bags seemed much more sturdy, and able to take the punishment of moving them around as needed.
From what I understand, the leadwakes bags are also lead from gun ranges.
