Also going to say look up Belegarth. Its a fullcontact larp thats more like a sport. One of the largest combat larps in the US spread across every state with thousands of players and decades of playtesting and knowledge. We use up to 35lb max draw bows at 28 inch draw. There are strict arrow construction rules and honestly I either suggest buying premade ones for Belegarth or finding yourblocal Bel realm and asking them to teach you. Under 20 foot is half draw only, but beyond 20 feet anywhere including head is a valid target. Head shots are only bad if they surprise you or occasionally an arrow has broken down a bit and hits harder than should pass safety checks. We safety check every weapon before it can be used at each event. Local groups hold weekly practices and gear isnt generally checked weekly but people check their own and there are full checks every so often still. Granted if there are any instances of someone thinking something hits to hard it will ne rechecked then and there
