RE: Marlin recoil for an 8 year old?
Hi again RJ,
The .22-250 should be the perfect stepping stone. I don't know anything about the rifle itself.....is it a full size, a heavy varminter, etc.......and is she average, small, or large for her age. If indeed is a full size insure her first encounters are shooting it from a supported position. As in a rest for the forend, (or bipod), to assist her with the size and weight of the rifle itself.
My wife isn't a small woman but because of her body style has difficulty with stocks that have average lengths of pull. She does much better with a "youth model" sized stock. And it's not the recoil so much that bothers her......as an ill fitting rifle.
Something to consider. Best of luck.....few things in life are as rewarding as passing on a passion to our children and grandchildren. Especially on those occasions when we see them "light up".......and realize we've found another person that enjoys it like we do.
