"for her without breaking the bank"
OK, that part is key, good advise above.
165-168 bullets, the Hornady 165 BTSP and 165 FBSP both work well in my 1-10
Higer end charges (so you can have reasonably full cases) of Varget, RL15, IMR4064 all work. It's just a matter of finding the load for yours. With Hornady at least you get 100 bullets per box so there's plenty for load development and still have some for making useable rounds, Can't go wrong with Sierra Gamekings either.
I found 2 accuracy nodes useing the Varget with the 165FB one at a mid range charge of 41.8 then another near max the of 44. I opted for the heavy charge but the lower node may be better for the ladies.
Hodgons lists on their web sight Youth and Ladies reduced recoil loads using H4895, it's the only powder they recomend for such reduced loads.
