I have hunted deer with one for over thirty years and it has never failed me. If you hunt "in the woods" it is all the gun you need. In the areas I am typically hunting in you won't see anything past 100 yards so there is no need for more gun (if I'm hunting an area where I reasonably expect longer shots, I use a different gun). I have taken a deer at 175 yards with the Marlin. That deer was crossing a pipeline and I did miss with my first shot, but once I took a breath, propped up against a tree, and took my time, the deer dropped with the second shot (the deer pretty much stood still after the first shot, I guess trying to figure out where I was). With some of the new ammo that is out there, a scope in the 1.5x-5x range, the Marlin will handle business out to 200 yards, but it's bread and butter is shorter range.
There is in life perhaps one fleeting moment when the courage, dedication and resolve of one man gambling against all odds will alter the destiny of nations.
