When a bolt gun does fail it becomes, a club.
Where the Bolt action Carbine length rifle comes into it's own in hunting is in thicker forests like we have on the East coast, Tracking through a northern Spruce ,or second growth forest, or through some of the Southern lowlands a longer rifle is going to be a PITA due to getting hung up in branches and brush. Secondly, your shots will not be at long enough ranges to benefit from a longer barrel. Honestly, unless you have a stand on a farmers field or hunt along Power lines, up here most shots are measured in feet rather than yards.
Dead on there, Tom.
For hunting, I like a compact rifle.
I posted on another thread a while back about my good friend (and long-range competitor) who, just for giggles, took a spare Remington factory bull barrel in .308 and cut it down to 16.5" and put put it on a stock Remington 700 action. It still averaged MOA accuracy out to 400 yards.
But to add to what you said in your post, he just got a 12 point mount back from the taxidermist last week.....he killed it on his property earlier this season, with the above short rifle, from his deer stand......the shot distance was less than 100'.
