Here are three recoil pads that I used on different 375H&Hs.

The bottom one was off an A-Bolt and was hard as a puck. The middle one was from a std 700 stock, also as hard as a puck.

The top one went on an old B&C stock with straight comb. It handled recoil 2nd to none. The other two, not so well. The A-bolt was brutal.
