Does anyone have experience with the Ruger 10/22 with the 20 inch barrel? On the Ruger website they list the rifle under distributor exclusives. How does the balance of the 20 inch barrel compare to the typical 10/22 (16.5 inches if I recall correctly)? I have a 10/22 from the mid-90's that is a walnut stock with stainless barrel that I have always been very pleased with, just wanting to add another 10/22 to the collection. I'm also intrigued by the 10/22 Sporter with the 18.8 inch barrel.
