RE: Managed recoil
bigbulls, I have the same issue with my daughter. When we started hunting a few years ago, we bought Rem 870s as our do-it-all gun. Well, I've since gotten a .30-06 and my daughter shot a round or two late last hunting season. She wants to trade in her 870 for a .30-06 now!!! She really did not like the recoil from shooting slugs from her 870, even with a rather thick PAST recoil pad.
Heck, I may even use the Managed Recoil loads for my ammo. We set up our stand in some woods and I've killed 4 deer over the last 3 years and they were all within 60 yards, so I'm thinking why not just use the Managed Recoil loads?
I think your daughter will be just fine with these loads.
