Best Bore Brush – Nylon or Bronze Phosphor?

Best Bore Brush – Nylon vs Bronze vs Steel

What’s the best type of bore brush to loosen fouling from gun barrels? And are they safe to use?

There are many different styles of bore brushes, tornado, standard, etc. There are also 3 distinct materials used to make bore brushes, bronze, steel and nylon. So which one will clean a bore more effectively without harming the bore?

Let’s talk about the new comer to the bore brush arena…nylon. Nylon bore brushes sound interesting and look cool but how well do they work? Well, from my experience they don’t perform well. Here is how I made that determination. I took my Glock 21 to the range and shot 50 rounds. I went home and cleaned the barrel with a nylon bore brush. After I was convinced it was clean (patches came out white), I then cleaned it again with the same gun cleaner but using a bronze bore brush. After using the same procedure of brushing 10 strokes and then wet patching, the patches came out black. They were very dirty. The bronze bore brush was able to loosen carbon fouling that the nylon brush couldn’t.

What about stainless steel bore brushes? I have bought some steel bore brushes in the past but ended up not using them. I just don’t like steel against steel. I don’t know what hardness the steel bore brushes are but I won’t guess and risk scratching a bore or muzzle. Why take a chance when you can use bronze? Bronze is much softer than steel and will not scratch or damage the bore of a barrel.

Bronze bore brushes work well and will not harm gun barrels. I only use Otis bore brushes because they are good quality and caliber marked.
