I put the Limb-saver on over my current pad and it makes the stock a bit too long. I will have to remove the current pad and try it again. I realized that I started out holding the rifle wrong when I got in the shower the other night and had the worst bruise I have ever seen. It was right on the top/inside part of my bicep. It looks terrible, but doesn' t really hurt. The little hollow between my deltoid and my collarbone is still tender though. I bought a ballistic shooting bag and will be filling it up tomorrow. I think this should reduce the recoil greatly for range use. After the new pad is on correctly, I think my problem should be solved.
As for changing to a different round. I am not doing that for a while. I bought a case of 10 boxes of ammo so that I would get the same lot # and hopefully have a batch of ammo with the same shooting characteristics. I wanted to sight in once and not have to do it again for a long time.
