Hello Lupe…I’ve just been jumping around here and I just answered another of your posts.
It is not important right now that you shoot a bow heavy enough for taking big game. If you put enough time into shooting any bow to become a good shot with it, it does not take that much longer to increase bow weight.
I started with a 5# bow when I was half your age and soon went to 15, maybe a year later to 30, then another year 35…and so on. A bow that is not too heavy and that you can enjoy shooting until you shoot it well, is the way to go. You will be using muscles that usually don’t use much…and you are still growing.
It is also important that you find a safe place to practice. This is an activity where safety rules…so that we can continue receiving enjoyment from it. Be Well, Rick.
