The problem is - you will not only polish parts you want polished for a smoother action but also parts that have intentionally sharp edges, like everything related to the trigger and bolt locking mechanism. Plus getting excess clearances might in some cases lead to worse operation than a very tight mechanism. So - imo - nice try, but no cylindrical smoking thing.
I used to love being able to hit hard at 1000 yards. As I get older I find hitting a mini ram at 200 yards with the 22 oddly more satisfying.
