The Marlin is a very light rifle and could cause slight marks on the shoulder from sharp lines. When Ad Topperwine shot many thousands of wood blocks with Remington Nylon 66 rifles, he was bruised quite badly.
People are like rifles. Some are tried and true, having great eyes, personality, and fun to be with. Others never seem to hit the mark with you. Still others go off half-cocked. Still, it's nice to know most of them.
