New cases

DM, I use bore foam as a final action to remove copper, it always seems to get what is left.

Personally, I don't use Wipe-out.

It does work but you need to leave it in the barrel for about 8 hours. Tested some once for the magazine.

Much prefer Sweets or ProShot copper remover. Both are very good and you leave it in for abot 10-15 mins and repeat until patches come out clean.

Interestingly, we took a borescope to the Training Weekend - lots of shooters don't get the copper out of their bore!

I am mindful of Ovenpaas previous comments re different products removing different levels and how one product can clean a barrel but should you then use a second, that the patch will come out with copper on.

Having a can of bore foam (Forrest's) I have just left the barrel for best part of 45 minutes. The instructions say 15 Min's.
The first patch through came out clean, so I cut a patch as large as I dare and that also came out squeaky clean.

I have to surmise that for me the barrel is clean, I am sure a bore scope may say different, but this is as clean as I will be running it.

I wonder if the 5R rifling has anything to do with how easy it is to keep it clean?

I leave my bore foam in for 45 minutes as well and I have a feeling Border or one of the others say shoot one, foam for 24 hours, shoot one etc. Great if you have a range in your back garden but it sounds excessive to me.

I have a theory about copper cleaners.... I alternate them, so swab and wait a few then clean, repeat and clean, repeat and clean and when it looks clean I do the same with a different cleaner. Finally Bore foam to see if I missed anything. I use a brush in the chamber as well to remove the carbon build up around the neck and then use a small bottle brush to agitate the bore foam.

Finally I have a squint with an endoscope which is a bit of a PITA as mine has a head that you can swivel around, I keep meaning to see if I can nail a camera to the end and use a laptop to view it :)

DM,
When you run in a new barrel, the only bit you are running in is the leade. Match quality barrels are lapped and really need no running in.

The chamber reamer cuts a ramp on the lands. The finish - under a borescope - looks like the edge of a file.

It also works like the edge of a file - on the first few bullets up the barrel - this is where the copper comes from. Subsequent shots vaporise the copper filings and spread it down the bore. Often, the biggest deposits are a few inches back from the muzzle.

After about 40 shots, the lands will be fairly smooth with just a few fine lines. After about 80 rounds they will be completely smooth.

Please try some Sweets or ProShot copper remover. Swab the bore with a loose-fitting patch and leave it for 15 mins, then push out the residue with a tight patch. If there is any blue, repeat. If not, clean with your usual bore cleaner.

Vince,

I have read a number of "how to" articles on shooting in barrels, but I don't remember anyone giving that explanation. To be honest, if you had asked me on Sunday why I was doing it I would have given a pretty blank answer along the lines of "because you do".
I thought it was to do with hardening the new steel.

I will try and get some of the Sweets or ProShot copper remover, but despite living next to Bisley, there are no decent shops within easy travelling distance,

Few gunshops stock Sweets but Fultons do.

Last time I tried to buy Sweets from Fultons they didn't have it, so I had to buy (expensive) Hoppe's Copper Terminator. After a good soak in old recipe Hoppe's the 'Copper Terminator' doesn't seem to find any more copper to remove.
