Shadowman,
Yes, you actually wrap the patch around the brush so that the brush itself (wich has to be nylon) never actually touches the bore.
You buy a brush that is 3 or 4 calibers smaller than your bore then wrap a slightly larger than normal patch around the brush to make up the difference in brush-to-bore ratio.
Shelf life seems to be as long as any other solvent. I used just 1 bottle all year long and it was as good on the last drop as the first.
The instructions that come with the product say something about oiling only if you are not going to shoot your gun for a month or so, but I have been running oil in all my guns after cleaning just to be safe.
4ked Horn,
I see that you have shopped SW before! SW has been out of my 300 grain MK's for months now! Maybe when they open Cabelas 20 miles from my home this fall, I will be able to get my bullets finally. /ubbthreads/images/graemlins/shocked.gif
One other thing I would like to add:
I just broke in the barrel on a .338 Lapua mag Improved today, and it has a 36" 3 groove, 10 twist Krieger 1.5" muzzle diameter barrel. It only took four patches to get it spotless for the first 8 shots. Then the barrel broke in and it was only taking 2-3. I got ten shots out of it in under 4 hours! I have broken in enough barrels with all the other popular solvents to know that I would only be on shot 4 or 5 by now, and Coppermelt more than doubles the speed of break-in. What used to take weeks now takes a day and a half!
I am VERY anal about doing break in right, and I am a local legend for wearing out brushes and using up whole cotton fields getting my guns broke in, but now it is easy. I shoot one shot and clean for the first 10 rounds, then shoot 2 and clean for the next ten, then shoot 3 and clean for the next ten. I also won't fire more than twenty rounds at a time until there are 100 rounds fired. Then I won't let it get even warm for the first 200 rounds.
And when I clean, if I detect even a hint of blue on the patch, I will keep cleaning until it is white,white, white!
I'm telling you that Coppermelt has turned this chore from a nightmare into a simple trip to the range one day. /ubbthreads/images/graemlins/wink.gif
