Get s stronger lady? LOL,
OK, seriously considered this one, lady shoots a Mossberg 100 youth pretty well - it's a 243, (308 is largest chambering from factory),
So if she had to go bigger get a 308 rebarreled to a 338 Fed or 358 Win.
Rifle she's used to, fits her, and has the UMPPPHHH to get there and get the job done.
Other than that, I'm a huge fan of brakes, but not because I'm a recoil wimp - it's because a brake allows me to stay on target and see the animal's reaction to the hit.
