Re: copper fouling photos
how bad is this copper and do i need to clean it all out, it take hours to remove. have used m-pro 7 copper remover,hoppes #9, and tetra gun copper solvent, all take hours to remove all the copper and im starting to get sick of it.

Re: copper fouling photos
mine looked like that yesterday. i used bore tech eliminator. after brushing and a few blue patches it didnt look any better, so i used some barnes stuff, which i believe is much like sweets. it worked much better and two more blue patches it was mostly gone. id say try the sweets.

Re: copper fouling photos
Hi Trev, yes that is pretty hard core fouling. From what I can see in the photo's, the bore could do with some lapping. You'll need to remove all of the copper fouling, then lap as per described in the barrel break in article. Go to Trade Zone (Croucher and Crowder) on Gill street for scotchbrite. Trade Zone stock Norton brand Bear-Tex pads, maroon 240 grit, Grey 600 grit and white which is good for swabbing with Eliminator or Sweets etc. You won't easily find Sweets at the moment locally, Dave at Magnum sports is having trouble obtaining it. Eliminator is fine providing you keep applying it, though you can leave it in the bore for a while and it will remain partially active after the initial contact/reaction.

Re: copper fouling photos
Trevor with the fouling of the barrel in the pictures how was the rifles accuracy and velocities compared to it being clean. Thanks for the pictures, good luck. Aj

Re: copper fouling photos
not sure of the velocities, im shooting with a chrony this weekend, all i was doing is testing out some different powder wights to find a max.. started at 42 and went up to 46gr of ADI 2208. anything over 45gr and the groups started to open up. but that could also be the copper? and more recoil, brass looked good all the way up to 46gr.
best was 44.5gr 2208 with 168gr nosler ballistic tip and over all length of 2.800"
after 45gn of 2208 the powder look's/feels like its compressed in the case but im not sure as im still a beginner with reloading.
anyway this weekend i with get the FPS for this load from cold clean bore, first 4 rounds then last 4 rounds hoping to shoot another 40 or so rounds. will put photo's up. of the bore after the shoot

Re: copper fouling photos

Re: copper fouling photos
first round 2559 fps, then 2557,2545,2545 fps. then 35 more rounds.
last rounds 2557,2617,2568,2582 fps
copper fouling was much the same.
will do some work on the barrel this week to try and cut down on the fouling.
my fist round is allways 2" up and 1" right. at 100 yards.

Re: copper fouling photos
I don't generally use ADI2208 (Varget) due to low velocities. You haven't mentioned which bullet weight you are using but if it between 150-168 grains, you may want to change to 2206h (H4895).

How was the accuracy?

Re: copper fouling photos
Nosler Ballistic Tip 168gr, its about 50 fps faster then the zombie max ammo with the same accuracy, about 1.5" in my rifle.
i need a new stock to get better accuracy, all in good time.
i will try 2206h when i run out of this powder.
thanks.

Re: copper fouling photos
Trevor,

Had the same problem with my Savage 243. Seven or eight shots and 2 hours to clean. Wrote a long letter describing the problem to Savage and boxed up the rifle and sent it back. They replaced the barrel with no hassle at all. Chatter in the barrel. Just started working on a new load and I haven't fired 30 rds down the tube yet, but no problems with copper fouling. So you may just have a bum barrel.

Re: copper fouling photos
hi, nathan. do you have any tips to share when looking at the muzzle like that, as to what an acceptable amount of copper looks like vs what too much looks like. or is it more when performance falls off. or signs to look for? iv noticed mine shows up on the lands, then as more shots go on it includes the grooves too. im guessing at that point its time for a clean. even though it seems to be shooting fine.
after i remove all i can see at the muzzle, and get clean patches. (my 7mm) im guessing its fairly clean. but in saying that. at about 230 rounds total now. it seems to show copper at the muzzle as early as two or three rounds,(on the lands) which i didnt notice earlier on in the barrel life. but i can shoot around 30 and it still groups ok. but i do clean the copper out at that point. (mostly to keep on top of it, and im finished for the day)

when you say it looks like the bore in the picture needs lapping, what gives that away?

Re: copper fouling photos
Your rifle sounds fine Jason. You must understand that a level of copper fouling is important. I have researched this extensively and will put the research into an upcoming book.

I determined that the rifle pictured needed lapping based on past experience. Some of the copper I can see is a touch on the heavy side, the color very bright and thick. The rifle would not need much work though, it is not looking too bad at all.

Re: copper fouling photos
ok. it looked heavier than what id seen on mine too.
i look forward to the books.
thanks.

Re: copper fouling photos
Has anyone thought of giving fire lapping a go? From what G D Tubb says it works and with his experience it wold be hard to say that he has no idea... although he is selling them. Has anyone tried the Final Finish and Throat management systems?

No need to answer previous post! Found it further along in another thread!
Cheers.
