What is strange about this hard carbon buil-up is that the rifle is a new Remington Model 7 CDL. Total shots fired = 10 (including 2 at the Proof House). Currently I'm developing a load, starting with 17.0 grains H322. After 2 rounds I gave the barrel about 5 passes with a bronze brush - but didn't repeat to check that all the carbon had been removed. I carried on and fired another 6 rounds before cleaning - but this time I double-checked to see whether the barrel was clean - it wasn't. I have now lost count of how many passes I've made and carbon is still appearing.

Edit: after much elbow grease the barrel is now finally clean. Could the carbon have been created from the initial firing at the Proof House if the barrel preservative had not been cleaned off ?
