RE: LOW RECOIL AMMUNITION?
How about just a little more info? What does she want to hunt? Where are you located (assuming it's for deer hunting, so we know how big they are there...)? How old is she? Any prior experience with guns? What are future plans... i.e. If buying this one for deer, are you looking to possibly use it in the future for something larger like elk?
I'm planning to use managed recoil rounds in my 7mm Mag this fall. It kicks considerably more than my .243, but a little less than my .30-06.
If you're looking for something that's mild recoiling, accurate, and perfectly suitable for deer out to 250-300 yards, your deer aren't the 350 lb. corn-fed Nebraska behemoths, and you don't plan to use it on something larger in the future, you can't go wrong with a .243. That's what my son and I have been using for the past three years.
