For serious archers only?

I may be misunderstanding your question. Is your accuracy off or the flight of the arrow? I get the idea that you're saying your arrow flight seems good at 20, but then as you go back it gets wobbly? You mentioned fletchings. That's the first thing I'd look into. Hard fletchings will throw an arrow off faster than anything else. I went to feathers years ago, and I'll never go back. I also use a helical twist to cause more arrow spin which stabilizes the arrow in flight better thereby making tuning a lot easier.

Second, are you shooting field tips or broadheads? My old Muzzy blades made my arrows fly pretty good, a one piece blade made them plane and do crazy things, and Rage expandables fly flat. There's my 2 suggestions. Add to it if I'm off base with your problem.

EDIT: Well, with that said, I'd have someone else watch you shoot. Make sure there is no new twitch you're unaware of at the moment you release. I know, I know, sorry. I didn't buy it either until a pro insisted on video taping me shoot. I couldn't feel it, but I could see it on video. Another suggestion is to make sure all of your nocks are set identically so you are getting consistent fletching touch the same way every time. And last but not least, use the same arrow for every shot. 1 arrow may be perfect and another may have an issue. I really hope one of my simple fixes is the key and that your cams aren't out of timing.

So, to be honest what you describe doesn't really sound like a problem with the rest. It actually sounds a bit like a spine problem in the arrow. As I'm sure you're aware, if the arrow is a bit underspined then you can get that kind of slightly erratic flight out of the arrow. The other possibility is if the fletchings are too small for the arrow and tip weight. If the tip weight is too high it can impact the arrow as it flexes in flight.

Now, if you've checked all of that stuff, then take a really close look at the release on the rest. Depending on the exact design, if the rest isn't dropping away consistently, meaning not at exactly the same time for each release it can also have that effect. Most of the designs I've seen have a spring that drops the release. In that sort of design, the tension can have an effect.

It's been awhile since I've tuned one of these. Good luck.

So what I am seeing is at 20 it hits in line with your sight, then the farther you go out the more to the left or right the arrow hits. If this is the case it might very well be your torquing your bow.

Even if your tune is off, once the arrow straitens out, usually within 10 yards, the arrow wont go to the right or left anymore. So if it is hitting on at 20 then it will hold that line for the rest of the yardages.

The best way to tell if your bow is tuned is to take a sheet of paper and shoot threw it with the paper only 5 feet from your bow. Then look at the tares. If it is just a good hole then your bow is tuned, if there is a tear to the right or left, up or down or any variation then your tune is off.

properly i might scrutinise Jeffery Archers historic previous and ask the question (Is he have faith worth?) additionally you may desire to evaluate that there are those secular dream interpreters that could say you're each and every of the characters on your dream. So ask your self what your preliminary feeling on waking up became. and then artwork out what area of your existence this dream may be (as your subconscious) speaking to you approximately. you're Jeffery Archer. you prefer to invade some alien place or individual. you are the only one that could comprehend why it is SO relevent to you.
