What are you guys using for dope cards? I had found some years back that Velcro onto the gun stock. They were cheap, the Velcro was strong and they have held up really well to all of the wear and tear, as well as the various gun cleaning and lube products. I need to update my cards, but I can't find these online anywhere. I'm seeing rail mount card holders that are fairly expensive. I'm looking for cheap, simple but mainly durable. I also had found some that attach to the sling. These have worked well too. And they keep the cards away from the gun cleaning products, which helps. But I can't find these online either. Maybe my Goggle-fu is weak??
