You may like the looks of a Decelerator, but you may find it too soft. I did not like mine at all in that regard.

I fixed this by filling the air holes on the inside of the pad with silicone caulking. Actually, you could easily adjust the firmness of the pad by filling some, all or a portion of the holes with caulk.

I had one fitted to one of my 9.3x57's, and did not like the softness at all. It felt like I was bottoming out on the pad when the rifle was mounted. It just "squished" too much for that rifle. Anyway, I filled all the holes and now have a "firm" pad that has held up very well.
