I unfortunately can't offer any practice tips that will make you a deadeye hunting shot at 30+ yards with trad gear. After 45 years of hunting and killing animals with gun and bow all I can offer is that, when you look back at it, respecting the animal and the 'how' part of pursuing them matters way more than bragging rights when someone asks "Did ya' git yer deer?". Somehow that steak on the plate after season's over just plain tastes better with that mindset. And if the plate has beef or chicken on it instead of venison, no matter. If I bowhunted mostly for meat then I most definately picked the wrong sport.
As Chet Stevenson always said, bowhunting is a short-range sport. Having hunted with everything from decked-out compounds to a simple longbow I absolutely believe him. As bowhunters there are better ways to challenge ourselves than to pray to the hunting gods that all the variables affecting long-range bowshots will somehow act in our favor as the shot is lobbed downrange at a moment of unexpected opportunity. No matter how good we think we are, the line between skill and luck is very narrow indeed when that multitude of variables, most of them outside the shooter's control, kicks in.
So don't beat yourself up over not being able to drill bottlecaps or bucklungs at 30+ yards with your trad gear. Maybe the bowhunting gods are just trying to tell you something.
