TK. You may have a point, but typically while cleaning the bore, if one drops the weighted end through the barrel, then turns the muzzle UP, the free end of the snake is hanging freely down, putting very little wear on the throat.
Embedding of grit is a problem with almost any cleaning method, be it a snake, aluminium rod, brass rod, etc. And sorry, but I'm leary of putting a steel rod in a steel barrel.
In my case, I'm at approximately 5000ish .22 rounds, and after 4 or 5 snakes, I haven't noted any visible wear, nor noted loss of accuracy.
