I just finished sighting in my 375 H&H, factory bbl. I used to have a 300 win mag that was absolutely painful to shoot. I have a wood stock. The Lady at the libsaver company said to just order the one for the synthetic stock and cut the plastic ridges off the back of the pad so it would fit flusk on the wood stock. It fits fairly well, although the toe of the pad was a little long, quickly fixed witha fine file. I don't have a guage, but the recoil of the 375 load I used is more than the 300, and it was nice to shoot, no bruises!
