Twenty-five yards is plenty far whether you are new to trad or not. It is kind of my self-imposed limit on big game, and I am a long ways from new.
Just work to improve your accuracy from 25 yards in and to improve your woodsmanship to get you there. Remember, your adrenalin is going to be working overtime when a game animal is in range, so be extra sure you are proficient inside of 25 yards. The area I hunt is pretty thick, so 25 yards is an awful long shot here.
By the way, welcome to the greatest sport/hobby/addiction known to man! Also, welcome to Tradgang!
