Re: Bore Life
This answer is based in nothing other than my personal observations of the universe.
I believe that the tighter the constriction (all else being the same) the longer the hot gasses will stay incontact with the barrel. The gases are hottest at the mouth of the case so this is where the erosion will show the most (because we all know that molecules are more prone to motion in a hot object versus a cold object of the same material)
Try this. Put an icecube on the counter. put your face very close and blow a lungfull of air straight down at it as hard as you can with your mouth wide open. Now observe how much it has melted as a result.
Now take a new icecube and do the same thing except this time blow on it through a stationary straw.
Hope this helps.

GRAVITY. It's not just a good idea. It's the LAW!
