A very light duty product - Gunslick Bore Brushes Stainless Steel - (8-32 Threads)

I bought these stainless steel brushes to clean a very corroded 450 calibre rifle barrel, the first problem was that the brush was a very loose fit in the barrel, also the shank of the brush was very thin diameter wire, which meant that it distorted very early in my attempts to use it, given that you would only ever use an aggressive stainless brush in a heavy duty cleaning job these brushes are not up to the job. In all, a total waste of money, given the high cost of postage from this company.
