I know the tubular feed provides a smoother lower profile to the bottom line of the rifle, but when I hunt woodchucks it is often from driving down the road and seeing them in nearby fields. Then a quick dash down a hedge row. Here, I cannot have rounds in a rifle in the truck...but I can have filled magazines. So, you can see where it's at..
With current production, chances fior accuracy are better with the Marlin #60 straight out-of-the-box, but if you are likely to get the "modifying fever", best stick with the Ruger..many more choices. In fact with Marlington/Remlin questions are rising.
I'm surprised that you didn't mention the Savage #64, another accurate rifle right-out-of-the-box..(like all Savages).

Or you cpuld opt for the "sniper" model..the trrsr..
