Newbie Question: Okay, so I have been looking at the Merkel K1 "Stalking Rifle" series and would like to know the positive (and say the negative!) aspects of a single shot rifle. *There is currently an offerring of a K1 series in various calibers with a Swarovski scope (3X10-42mm) for under $4,000.00....much cheaper than a nice double rifle as currently manufactured. The single-shot premise interests me and the K-1 is a handsome rifle. Thank You.
