Has anyone used one of these things on a regular basis to clean their bores? I would appreciate any input good or bad on these bore cleaning systems. They seem like a good idea but I'm not sure if they are bad for repeated use or maybe they just don't plain work. I would use it on bolt action hunting rifles, old military surplus and new semi-auto rifles, mostly copper ammo.

I have been very happy with the copper and lead removing capabilities of the Foul Out system. I do not use it every time. Just about every 3-4 cleanings or at the end of a season. If you want a bore completely thoroughly clean of metal fouling, this is it IMO.

Thanks for the input whiskey, I'm thinking of sqeezing the trigger on one of these units which seem pretty reasonable considering what they do.
