Was shooting dogs today and realized that after 500rnds my wrist was getting sore. Started me thinking that a pistol grip design might reduce that. Anyone have experience with this? I really like the Fajen thumblehole sillouette stock, but have never shot one. Also, looking through Midway, I noticed 1:16 barrels. Whats up with these? Still looking for direction on the new project, but might be on to something now.
