Buildup in barrel

[Brandon101884]

Anyone have any solutions on getting this buildup out of the barrel? It was clean and lubed before todays session. Went through around 200 rounds of buckshot and some slugs. Nothing crazy. I’ve got hoppes bore cleaner to try and get it out and it’s not budging.

Get a cleaning rod that you can mount to a power hand drill. Here is one from Brownells although others make them or you can make your own.

Would that much friction with the bronze brush damage the barrel?

It hasn't damaged any shotgun barrel I've ever used that in. Barrels are tough and they're smooth bore, it would jack up rifling though. It's the same method you use to polish the inside of the mag tube and they're not barrel steel. I've had buildup that, no matter what I did, would not come out and that got it out. The brush is bronze, much softer than steel. That little bit of buildup isn't going to affect the shot anyway though.

Use a Hoppe's tornado brush with a cordless drill -

This was the only way to get all the leftover Led from slugs out of my barrel.  I have read about using harder slugs reduces this cleaning but yeah it’s a process.

I recently cleaned a police trade in barrel that looked like it had never been cleaned in it's life. I really thought that barrel was maybe toast when I first looked at it. I remembered reading that something was good for wad fouling... either WD40 or brake cleaner. lol I laugh now because I can't remember which... but knowing where I did the work, I don't think there's any WD40, but there is brake cleaner. (and that makes a lot more sense I think. lol) That and a regular bore brush made the barrel spotless.

Wd40. Spray in barrel, let soak and hand brush (no drill). Clean as new.
