I practice/shoot regularily further than I would ever consider on a game animal and have found it has made me better at my hunting ranges. If conditions are right 45 yard shot is about max I will take on any game animal, in reality I have only shot 1 animal in that area the rest have been 35 or closer. So if you can confidently set a 40 yard max range you'll be more than set come elk season, but certainly wouldn't be worried if 30, 35 or whatever is what you set it at, just be realistic.

Practice how you'll hunt, meaning vary the shooting position, shoot on windy days, tight situation, wet weather, cold, etc. Then you'll know what your limits should be in terms of field or real life conditions you may endure on any hunt. Be honest with yourself and if 35 is stretching it than don't put yourself in a situation you may regret better to pass than leave with an arrow missing from your quiver and poorly stuck in an animal. No different than a rifle or ml really, they all far more capable than their shooters in most cases but you must adhere to your limits based on abilities.
