I have been shooting with a glove for a long time. A few weeks ago, on a whim one night, I tied taking several shots bare finger. No glove, no tab. Naturally, it made my fingers sore after a few shots, but I noticed an IMEDIATE tightening of my shot group. I mean substantial. From a decent-but-not-great spread hand sized group to a pretty tight knot of arrows in the target. This caught my attention. Since then, I've been shooting more and more shots every day bare finger. I'm at the point now where I can shoot a lot-enough that I lose count-without being sore and my shooting has really improved. All else is essentially the same, but my theory is that with bare fingers I am twisting the string less, coming nearer to centered under my eye at anchor, and getting a more consistent anchor point. I don't know if any of this is true or what exactly the reason is, but I can see the results and am very pleased with it. And, it's one less piece of stuff to have to keep up with and carry around in the woods this fall.
I am wondering who else has tried this and what have your observations been? I have seen that my good shots are anywhere from the same to slightly better, and my bad shots aren't nearly as bad as they were. They are now decent shots still in an average sized kill zone rather than off in left field somewhere. I am pleased with this.
