when you're out at 10' and out are you using feathers or bare shafts? Probably a dumb question, as there is no way for the shaft to correct itself without feathers. Which is the main reason I posted to begin with.
paper tuning DOES work...or should it say CAN. Just like group testing (which is easier, kinda like walking into a fast food joint vs driving through the drive through. they both get the job done, one takes slightly more effort) That said the one that takes more effort I personally believe gets you better results in this case for MOST guys.
Some of your issues with bareshafts/paper tune not being consistent could be you! how often do you check your BH? strings move...both strung AND unstrung, which is going to change how your bow shoots. B50 is worse than the 'less'stretch strings like ff d97 etc. Skinny strings (atleast mine) move also when stringing and unstringing more than my old 15 strand d97. If they move enough they'll greatly change your tuning! I rarely unstring anymore, but try it some time after being strung for a month check your bh before you unstring it, and than restring it a few days later. It could also come to you and your consistency behind the bow, on the string or a host of other small factors that creep in and out from day to day. Bareshaft shooting/ paper shooting will show you these immediatly. The problem people have with it is this. they dont believe or have been led to belive they dont shoot good enough to bareshaft tune....ie their shooting flaws get in the way of real results. If you shoot more than a couple days a year I dont believe this to be true. Sure some guys are michael jordans of the bow world and other guys like myself should probably stick to using them as canoe paddles. Those dream team people can do no wrong and people like myself do no right. The difference is usually form....consistency. They go hand in hand!
There is no wrong way if it works. There IS easier ways. Shoot enough arrows and you'll get a consistent reading bareshafting/papertuning. Dont move on just one shot! Its quite easy to bareshaft out to 20 yards....the farther you go, the closer you have to be to perfection in spine, form, consistency, bow tuning. A few twists off on the string will break a POC at 40! If it doesnt fly, your tuning is off...the final question becomes what is 'good enough'? The more distance you add the more those small flaws show their ugly heads. Ad a bh on a rainy day at 25 yards with a little wind with a poorly tuned arrow...goofy things can happen!
the closer that bare shaft flies, the better things will be with feathers all around!
