The Konocti Rod and Gun Club, a few years back, decided to build some shooting benches, with steel frames, and concrete tops, for our range. The plan we had was for a right hand only bench. Just on a lark, I asked if we needed to make one left hand bench, just in case there was a lefty in the group. Boy, did that open a can of worms. As it turned out there were seven southpaws at the meeting, who until I mentioned a left hand bench, thought they would just work around the right hand only benched. Our benches are all ambidextrous now, and, more left hand shooters came out of the closet after we started building the benches.
I also own an antique muzzleloading rifle built in the late eighteen hundreds that has a right hand lock, but has a left hand cheekpiece.
