My wife has used the 240 XTP and H110. It's a little much for her, and too much for the little kids. I started my boys at age 10 with the Hornady 225g FTX and a medium burning powder.
For practice, I loaded a 180g cast lead and a fast powder. I found a load that hit close enough to the hunting load that we could practice on steel targets with them.
I am sorry that I don't remember which powders I used. They were just picked out of the book based on what I had on hand.
I have four sons, three who are big enough to hunt with me. They all have different body shapes, sizes, strength, and recoil tolerance. Most do fine shooting as a group, one needed one on one time with me to enjoy shooting. In other words, every kid is different, and shouldn't be taught or judged the same as other kids, even siblings.
