Thread: Copper mine

Tried to get a pic of my AR 6.8 barrel after 15 shots. Has had about 120 through it total.

This is about the worst copper fouling i have seen, is it even that bad? Still shoots OK.

That's shite.. What bread is the barrel?

By alright i mean about 1.5" at 100m average which is good enough for what I want with this rifle. Its got a pretty lightweight barrel, the whole rifle with scope ect is only 6.5 pounds

Fire-lapping a bad idea?

Give it a jam and let us know

You can give it a good wank with JBs or Autosol, BUT your copper extends all the way to the crown....

Shoot it clean.. if its same when fouled then ignore it

I have seen worse but that's definitely copper

Could it be related to the projectile being used ?

clean the hell out of it,make sure there is absolutely no copper left in it.
load a few blanks and fire to carbon barrel.
This can help a lot.

My last 4 rifles would all copper foul like that - even after only a few rounds. My current rifle - will look like that after only a couple of rounds and yet all my previous rifles shot well and my current one is an absolute machine. Doesn't do a cold/clean flyer - I've never not found a sub moa load for it in over 5 different projectiles including the finiky LRAB - only ever used factory ammo in it once and that was for shooting her in - and even that shot sub moa after 2 sighters to get it on paper. So I've come to the conclusion that we/people get antsy about having copper showing in our barrels and can chase tales all day long - yet if it shots then why worry?

Will give that a try, my groups are the same dirty or clean and relatively the same POI so not to worried, its only a rattle gun. I have just changed to a faster powder and im getting bugger all carbon fouling.

I've got some jbs if you want some . Used it on advice from the forum , on my 223 that was fouling bad . Worked well
