looking for a decent rifle rest to shoot off a bench and maybe a wooden tower. I'm using the $25-30 Caldwell bags now but they got wet and are hard and don't really hold the front of the rifle well even when not hard. I'm trying to see what this rifle can really do on a bench with my reloads. looking at Caldwell rock rests but someone recommended the other bag the holds like 3/4 of the rifle. any thoughts?
