Higbean,
I've generally found a softer forend rest helps light rifles more than anything. ALL rifles will recoil away from a harder rest, even rimfires, but its exaggerated in light rifles, and even a sandbag that's compacted some will cause it. So with any rifle weighing 7 pounds or less I fold up the terrycloth towel in my range bag, and lay it over the sandbag.
I don't bother holding the rifle differently, and just put the middle of the forend over the towel, just like I would if hunting and using a daypack for a rest. Have never been able to see any sense in hunting with a rifle that requires a "special" hold to get it to shoot well, and a towel has so far allowed every light rifle I've fooled with to work the way a rifle should.
