My wife and daughters all wear electronic muffs. Even my 2yo (we are amazed she wears them "happily") I do also with every other caliber. Maybe I should with 22 but......... I guess I don't have a great excuse.I don't see a can on the rifle, You need to reconsider the no muffs, especially for your daughter. Even though it's not as loud as centerfire it still damages your hearing.
