My Ruger likes 35gr Remington ballistic tips, but they are very expensive.
My mate gave me about 500 rds of winchester 40gr soft points and the gun does"nt like them(3"-4" @ 100 yds), but my favourite at present is the 40 gr CCI Maxi Mag. Affordable and acceptably accurate in my rifle. I tried the Maxi Mag Plus V ammo(35gr?) but they were the worst groups of all, barely could keep it on an A4 target at 100 yds. I can reliably hit a rabbit at 115 mtrs, any more is a bit of a push, esp if there"s any wind.
Hope you find a round she likes, .22 mag seems to be very choosy!
