TAB gear is my personal favorites. Anything they make is great. I have triad tacticals to that aren't to bad but my pack has to TAB gear and that usually gets me. Had to take 2 cold bore shots today at 520 and 630 and couldn't go prone and had to set up on these bags. MOA hits both times. THese bags are made of strong materials and will hold up to abuse. THey make slings, shooting mats, rear bags, suppressor covers, and other shooting supplies. IT is owned by Thomas Burke of Alvin TX and is absolutely great to deal with.
You know what my favorite bags are? Homemade ones out of old bluejean pants legs and filled with sand. Sew up one end really tight. Fill about 3/4 full of sand, then sew up the other end. They work just fine. 2 in the front, 1 in the back. That's how I shoot all my groups, unless I decide to take the Caldwell tackdriver bag for the front, and use a sandbag for the rear.
