It was early to mid 1980's...Colo. Spgs....handled a BSA bolt action....the caliber?....I don't remember...larger than a .22 rimfire. Had the slickest action I had ever seen for a bolt gun. Never bought it. Been looking ever since....but I am under the impression that BSA only made .22 rimfire. I have been unable find anything used... in a larger caliber. Was I dreaming? Did BSA make larger calibers? This was a new gun. Been kicking myself ever since....shoulda...coulda woulda.....
