>>129889040 lbs or less is good for starting out.
Because your gonna have to shoot a LOT! and shooting with 50 lb + bows for multiple times a day in Hot weather, is not reccomended.
Also If your gonna use a TRAD bow without any riser, and shoot off your hand. In order to not hurt your hand you MUST nock the arrow higher than where you grip the bow.
A good principle is nock the arrow so that when you let the arrow fall it is pointing down at a 90 degree angle. This way you wont hurt your hand.
Also learn to get a rhythmn of shooting. And dont expect to suddenly be able to hit a rabbit, or small target from far away like it is nothing. Hollywood, video games. Are not realistic depictions of archery. Even people who lived off the land hundreds of years ago would occasionally miss their target.
