brass or plastic brushes?

[esminbritt 16]

My saiga .308 came with a plastic cleaning brush. If I switch to a brass brush, will it damage the chrome-lined bore?

You realize that chrome-lined bore stands up to bimetal-jacketed bullets being pushed down the bore at 2800 fps, right?

 

Bronze brushes are fine.

Yeah brass is a lot softer than chrome so it's fine and dandy.

Yeah. that makes sense now. Why in the hell do they give you a plastic brush. As if, in combat or at the range, you're suddenly gonna need to brush your teeth. Cheap Russkies.

The only reason I can think of for the plastic bristles is to allow the scrubbing of the barrel with a solvent designed to remove copper deposits. For some reason it seems to me the use of a bronze brush [copper with tin and some other metal] would not be the wisest thing to use with a copper remover solution. I would think the solution could start to affect the brush and cause it to desolve, leaving more copper on the barrel to begin with.

 

Just a thought.

 

Anyone else able to clarify my thinking? I don't know the above: I am just guessing and love to learn from those who actually know [not guess, like myself].

I was always told to eschew brass jags and bronze brushes when using an ammonia-heavy copper solvent.
