I’m not trying to derail the thread but I have read a review in outdoor life about a left hand bolt right hand ejected rifle I believe that was made by shilen. It was designed for prairie dog hunting, and being fired exclusively from a bench/bipod the left hand bolt handle allowed you to keep your cheek wield. It had a thumb hole stock to keep it out of the way and a 223 length action didn’t require moving your head. Interesting but very specialized.
