Cleaned with Coppermelt after 30 rounds. I use a 6mm nylon brush for my 7mm bore. One thing Iíve found is that some of the 6mm brushes are different sizes by a little, and you may need to reduce them as needed.
One thing is that I only use about 5 or 6 strokes on the first patch. Thereís something about knowing how dirty the first will be that wonít allow me to use 15 strokes on the first patch.
Sometimes if Iíve fired more than I should without cleaning I will run a patch wet with Coppermelt on a jag through and let it set for a couple of minutes and then do the wrapped patch routine. After that it only takes a few minutes and youíre done.
