I have recently started shooting my recurves a lot more in preperation for this fall. I have been shooting pretty good but have been having problems with my fingers. I shoot three fingers under and have been developing an enormous blister/callous on my ring finger(third finger down). I have never really had this happen before and don't know how common it is or if there is something I should be working on with my release. I almost feel like I might be plucking my fingers and dragging that third one a bit. I don't know, any thoughts?
