I started my daughter on a 50 cal smoke pole and just reduced it down to 30 grains of FFF just to let her get used to it, she was 12 at the time. By the 4th time out practicing I kept telling her we were going to bump up the powder each time till we got to my normal load, she shrugged and said ok. So over 4 trips and probably 40-50 shots we worked up to the 80 grains I normally shoot. Just kept creeping up 5 or so at a time so it never had a "WOW" factor to her when she pulled the trigger.
