[QUOTE="Jud96, post: 1867404, member: 69478"] I recently did some load work up with my .308 Norma Mag. It has a Bartlein barrel on it with about 200 rounds on it. I decided to completely clean it down to bare metal to remove any jacket material from the Hornady bullets since I was going to be trying Bergers. I have never cleaned it this thoroughly in the past. I only ever cleaned it a couple times before and I just would get the carbon out and leave most of the little bit of copper in it. Well I ended up getting higher velocities about 25 rounds into load development. The same exact charge weights were 30-40fps faster after having the barrel fouled in than when clean. It threw me off, but I narrowed it down to the barrel needing more shots than I expected to foul in completely. [/QUOTE]
