Savage barrels are known for being accurate but also known for having a rough bore causing rapid copper build up and long cleaning times.
I totally agree with the above. My OEM Savage barrels are very accurate, but I will probably use 25 patches during cleaning. Also I have to start with a bore brush.

On the aftermarket barrels, I just use chemicals, no brush, and 5 to 6 patches max to clean them up.
