I'm having some issues with my Samick Sage. At 10 yards, the bareshafts are pretty good. But out at 20 yards, they plow into the ground a foot or two in front of my bag. Left/right is ok, just plummets before hitting the bag. That said, I've bareshaft tuned all the other 6 recurves I have and they all hit right around where the fletched arrows are hitting. I am shooting off the shelf and I've tried running the nock up and down, even to the extremes. I knock my arrow under the nock and I've had the nock all the way to flat level and up to 1" high and no matter what, it still digs in. It seems to be closest about 3/8" high but still probably a foot low of the fletched arrows. And I'm getting contact on my hand at that height. Is it possible it just hates being shot off the shelf? Seemed ok off a rest but I didn't bareshaft it that way.
