there was a very good and legnthly article in precision shooting magazine in jan.2006 regarding bore cleaning.
theres no doubt barrels can be ruined with solvents.
there is also no doubt bad barrels may only be fouled barrels. i know that from personal experience.
the article was a 2 year study, mainly because of never ending new products.
ALL of the bore cleaners were practicaly useless for copper fouling according to the author
except 1. that 1 is bore tech eliminator. that said it does not do well with carbon. again only 1 product was found to deal with that effecivly.
that product was intended for cleaning fuel systems.
even the heavy smelling stuff like sweets was considered useless.
bore tech has a complete line of cleaning products. eliminator was the only one reccomended, and that for copper fouling only.
the other product is called slip2000 and was reccomended for carbon.
that company apparently seized upon the oppurtunity and is now also offering a full line of cleaning products also. www.slip2000.com www.boretech.com
i recently received a copy of this from a shooter friend. i have yet to try the products but i certainly intend to.
