I'm looking to upgrade my daughter's hunting rifle. She has a rossi 223 now. I'm looking into getting her a 243 in either NEF single shot, Savage Edge, Remington 770 or a Marlin XL7. Has anyone tried any of these.My daughter is eight and looking forward to taking her first whitetail. I will also be reloading so if there are any pet loads for these rifles let me know.
