I bought a single six with both cylinders and the long barrel (10-12"), and i took dozens of rabbits and rockchucks with it. One chuck was at approx 100 yards and then and there i was hooked. Sold that gun and bought a tender with a 14 " 223. That and a new 686 6" became the start of buying and selling and trying about every caliber known to man.
Now my other love, black powder cartridge rifles.
