Ravenwolf,
In familiarizing your daughter with the rifle, confidence is the key! Let her shoot it like you would a .22. A load that I developed several years ago for this very purpose (makes a fist class small game load too) is listed below:
.310"-115g FNPB/7.0g Blue Dot/Any Large Rifle Primer/Mixed Brass/1200+/- fps.
This load came about when seeking an economical plinking load for the .30-30, looking on my powder shelf sat a lonely 8 lb. canister of Blue Dot. I reasoned that with 7,000 grains per pound, and a load of 7.0 grains would yield 1000 loads per pound, and that 8 pounder of Blue Dot would be about a lifetime supply of center-fire plinking and practice ammo. The surprise came when that load delivered a virtual ragged hole group at 50 yards with all of our .30-30's at the time, both Marlins and Winchesters as well as an NEF and Savage 24.
The key is to seat the bullet to lightly engage the lands of your rifle when chambered. A crimp isn't necessary, but if you desire one the Lee Factory Crimp Die does a first class job.
The load has the recoil of a .22 Mag rifle and the report of a .22LR! It is very economical, does not wear the barrel, and will give an unmeasurable amount of confidence to your daughter's shooting ability. Interestingly, this load shoots to point of aim in most guns out to 50 yards when sighted in with the typical 170 grain factory loads at 100 yards. It hits with the same authority as a .32-20 on target, so is no pop-gun.
The main thing is shot placement with any shooter using a .30-30 Winchester, and practice, practice, practice is the only way to instill confidence and proficiency to attain that precise bullet placement. Most shooter's flinch is from either a poorly fitted stock or the noise factor associated with the load. Let your young shooter fire a pile of these loads, and switching to factory equivelent loads she'll never know the difference in reciol when pulling the trigger on her first deer!
Of course you can tell this is my totally unbiased and objective point of view! :biggrin:
God Bless,
Marshall
