I know what you mean about it being a small gun amd fit. I'm 6'2" 220lbs myself, you've got 3" on me. But a lot of my shooting is done with a heavy coat on so the shortness of the stock is just right for me. On the bench during the summer I use a padded shirt or padded jacket to get that added length and to keep the scope off my nose.
I used to carry pumps, and lever guns, for fast follow up shots. Then I started carrying bolt guns. Then one day I realised that I seldom need a second shot, in fact in 45 years of hunting I have only needed a second shot twice. I no longer feel I need to carry a repeater, a single shot is totally adiquate for me. I also hunt in Grizzly Country, but I still carry nothing but single shots. During the Spring, Summer, and Fall hunts I carry a single shot in .338(T/CR), or .35 Whelen(Handi). During the Winter I carry a 30-06 Handi exclusively.
