I bought my wife a Winchester M70 Featherweight in 257 Roberts, found a really good second hand one over here.
We had about an inch cut off the stock, then a 0.8" Decelerator added to it.
She shoots 85 Ballistic Tips with AR 2206H (H4895).
I started her out on a load of 28 grains, a youth load, and every time I load ammunition for her, I increase the charge by 1 grain, without telling her, so far she has not picked the difference, and is now shooting nearly "full power" loads.
We are off to the range tomorrow, she wants to try my 35 Whelen, I have loaded some cast bullets at about 1600 fps so she can get used to it as well. After a while I'll graduate to jacketed bullets and a bit more speed.
After all, I want her to keep shooting with me, not to have her give up because "it kicked too much" no point in that at all.

Regards,
David.
