Hey thanks guys!
I don't think recoil is going to be too big of a problem as she shoots a 12 ga. just fine and loves shooting my Stag Model 6, even though that recoil is non existent. No, I won't let her use that as I know it takes a great marksman to make an ethical shot with the 5.56. Thinking about probably strapping a Vortex scope on it, as they have amazed me with how clear their optics are. I do like the .243 because there are a ton of different options in rifles for it. We'll be hunting in the high desert of Oregon where a 200+ yd shot is pretty normal. Which is the main reason I was thinking .270 for that little extra knock down power.
