Been working up some loads for my AR 25 WSSM and I've been having a heck of a time with copper fouling after only 5-6 rounds. Any ideas why this is happening and how can I fix it would be appreciated.

TUBBS final finish. My guess is you are dealing with excess tooling marks in the factory tube.

117gr SST's ove 46gr of W760. I also got good groups with 48gr if W760 but started to get flattened primers.

Re: Excessive Copper Fouling!!!
I'd try some JB bore paste and work the throat very well.
You can "feel" the rough spots smooth out.
Some sweet's 7.62 solvent should be used first to try to dissolve as much copper as you can.
(clean out all ammonia after sitting for 10 minutes)
Tubb final finish bullets could be used as well.
With quality barrels, this will almost never happen.

It's on an OLY 25wssm AR15 upper so not sure who made the barrel but it is SS. I'll give it the JB treatment and see how it works

+1 for sure, this is what I did to my LR-308 and it worked wonders.
