My 80 lb., 9 year old, grand daughter shoots my fathers Rem 600 in 243 with no problem. It's a small rifle with an 18 1/2 inch barrel and is pretty loud with that short barrel. By the time you put a scope on it and add a pound in weight it puts it at 7 1/4 pounds. I don't think she would do well with a heavier rifle just hefting it around.

Use muffs while practicing and she won't have any problem. Your daughter may be stronger and handle more weight okay but you have to judge that.

If you go with the 243 stick to bullets around 100 grains. Sighted at 150 yards you can shoot out to 175 - 200 yards without any allowance, but I'd recommend setting up for a 125 - 150 yard shot max. if possible for a first timer.

If you go with the 30/30 scoped the recoil will be about the same and again try to keep shots under 150 yards.

Make sure she snuggles the gun in nice and tight so the recoil doesn't get a running start at her.

Marksmanship is the key so the NEF single shot will do the job on the deer. If you put the first one where it should be you won't need the quick follow up shot. The NEF will probably be a pound or so lighter so there will be a little more recoil.
