I fortunately had a good teacher my Grandad a retired keeper and my Dad who caught a lot of rabbits. But that was the basics, I poached my first deer and got thumped and castigated for it. After that helping a keeper and cutting lettuce for a farmer got me the chance to shoot more deer, even if it was with a rimfire and hornet.
It wasn't an easy way but I was lucky and willing to take opportunities to learn.
Well done the Op for offering that chance. We are starting to get my assistants lad interested and he is very keen to learn.
