[RC20]

Yep, both product listed have proven to work.

I use the Eliminator as I don't have much copper and there is alwyas some carbon in the layers (old guns)

While my approach is a bit different, what helps a bit more is a warm barrel so I do it at the range when I am done shooting that gun.

Regardless the old stuff was toxic and brute force approach.

You don't have to worry about poisoning yourself or making family sick or gloves with the new stuff.

And with a bore scope its proven to work not an look through the barrel opinion.

Frankly it would be like someone made a reasonable cost shaft drive bicycle with full suspension. It would not be any better.
