I know what you're saying. I have two of them and it took some time to "learn" to get it off my shoulder. But once you have it, and practice with it... its actually comfortable.

If you dislike it that much might I suggest sell it and get a Lyman Trade Rifle instead. Or as suggested. A large rubber butt stock cover could be installed and then that would solve the problem. Although I would lengthen the LOP.

If you were to cut the "horns" off, you could add a new back plate of some kind. It might not look to bad and be what you want.
