I am doing my barrel brake in and i am noticing a huge amount of copper in my new barrel after one shot. I am doing the one shot and clean and its been a choir! The barrel is a gain twist krieger. Does the gain twist have anything to do with this? I wouldnt think so but i am baffled by the amount of copper this barrel is collecting with one bullet going down the tube. I can see the copper inside there when looking in the muzzle with a light. Does this just sometimes happen, will it clear up?? Do i have anything to worry about? I dont want to call Krieger if this is a common occurrence. Any thoughts? Lee

Try running a patch of Kroil through the bore then fire it.
This should make it a little easier to clean,,I've had some barrels that have taken 50+ rounds before they clean up..
If you need some ill bring it by and leave it on your porch..

I have been using JB on the throat of a fresh chambered barrel to help smooth out machine marks and small burrs left by the reamer. You are breaking in the throat maybe as much or more than the barrel. The throat is rough from chambering it can leave much copper all the way down the tube.

No, I wish i did!! I dont think there is any major problems yet. I was just a little shocked to see the copper in that amount with only a single bullet down the pipe. I am still learning and this wasnt something i have seen before. I did a bunch of reading and talking with my smith and Krieger and I have come to the conclusion That there isn't any problems as of now. I will shoot it this weekend for groups and see where I am at after 50-60 rounds. If it continues I will spin the barrel off and have a closer look. Thanks fellas for the info I do appreciate it!!!!

Lee, I suggest that you read and, fully understand, the last 2 posts, on the "30 cal 3 groove Lilja" thread in "Advanced Gunsmithing". Francis and Al have summed up these "Jump the Gun" reactive threads for just what they are. BS!!!
