I have been messing around with Staball Match as a replacement for Varget in my 6BR so I can drop powder on my 750.
I have been finding it seems very dirty and carbon is building up FAST in my chamber. Groups start out good - at least 0.5moa and great SDs of around 8 on a clean barrel.
After about 150rds, brass gets hard to eject. Not heavy bolt lift, but hard to pull bolt back. I noticed that i get a carbon ring building up on the outside of my brass necks.
I stuck my bore scope in the dirty barrel/chamber and the carbon in the chamber seems crazy.
I never see stuff like this with Varget, even after long cleaning cycles of up to 500rds. I knew this stuff would be a little bit dirtier but this surprised me.
