Cleaning With A Nylon Brush
 

I use a bronze brush that won't stick in the bore or pull apart. I've used it for years with no problems. I'm not a fan of nylon brushes. They don't scrape hard enough.

IMO if you clean your bore very soon after cleaning the fouling doesn't have time to harden up and a nylon brush would be more then enough. But I use both bronze and nylon brushes.
Semi I don't know if I'd like that idea of epoxying a brush in a dowel. I have all my ramrod ends pinned because I have a tendency to use really tight patches. I can see that pulling out of the dowel and getting stuck in my bore.
Call me paranoid but having a brush stuck in a wet bore is no fun.Occasionally I was able to blow them out with my compressor. Other times I had to shoot them out. (That's why all my rod ends are now pinned!)

I think brushing would be more important for those who shoot lead conicals. It's the only time i've felt a need to use a brush. Soap and water flushing is all I needed when shooting a PRB.

Nylon for me as well. They last a lot longer.

If you can clean straight through the barrel, bronze is really nice, especially for removing lead/plastic.

Bronze once in a while, but nylon 90% of the time.
The cleaner is more important than the brush-type you use.
The patch material is more important than the lube on the patch material.

Hi Pete, Clem & Van! Hope you're all doing well.
