Interestingly she got behind it better than she does a Savage Rascal, she always wants to tuck the Rascal under her arm, but she did not even try that on the Rokstok.
From a trigger perspective, the Rokstok is better than the Rascal and with a little work I think she could drive it off a rest ok.
However, unless shooting off a rest, and having me help set the rifle up, no she could not hunt with it. The sub 3 pound Rascal is pushing her in the strength to comfortably handle department. The 8ish pound Tikka/Rokstok rifle is 1 fifth of her weight (I would not want to use a 36 pound rifle for hunting, which would be an equivalent weight ratio, though 50 or more pounds would be closer on the muscle mass to weight ratio).
Your daughter has 20 pounds and 7 inches on mine, so not a direct comparison. If hunting from a still position, I bet it will work well, particularly if suppressed. I think the only think is to try both (as you will have both) and see which she claims.
