Probably some will say it's from bad release,that is too much pressure on the ring finger. Iv' developed quite a build up of calloused skin on my ring finger.I have tried shooting with more pressure on my other two fingers, but it just doesn't work for me. Maybe this is more common than we think among us trad shooters. At any rate, It works for me and the calloused skin has been earned. I consider myself a fair shot even with my disability. If your shooting well.......callous on!!! :D PS Once your finger callouses more it won't bother you at all!
