On the load, i use a 50 gr pellet behind a 250 gr bullet. She has had 3 pass through kills. 25 yrds - spined, 70 yrds double lung, 50 yrds shoulder & lungs. Read about this loading in a Bill Winke article and it is supposed to be fine out to 100 yrds. By the time she is good enough to shoot that far we will probably be using more powder anyway.
One other trick is that i have her practice out to 50 yrds, but use a 30 gr pellet so she does not get a flinch or worry about the kick. Then I put in a 50 gr for hunting. She still does not know this, but always says she felt no kick when shooting the deer.
Hope this helps.
