RE: Women hunting, less recoil options???
probably be better off with a Powerbelt and shooting Loose powder. Powerbelts will perform excellent with low powder charges, expand easily whereas with a modern pistol bullet, you may have to push it much harder for it to expand.
If shes shooting a .50cal i'd take a look at the 223gr Platinums or the 223gr Copper series and try 70-80gr Pyrodex RS.
