I haven't paper tuned for years. Walk-back tuning with field points and broadheads for me. There are so many variables that can produce incorrect outcomes that it's all but unattainable for the average archer.

One of the issues I have with paper tuning is that it wrecks a shooter's confidence. They can't get those perfect "bullet holes" at all ranges so they head out with that dark cloud over their confidence. And guess what? If you think you're going to make a poor shot, you will talk yourself right into doing just that.
Archery is very much a mental game when comes to letting that arrow go.

And besides, I don't shoot very good anyway, how good does my set-up have to be?
