[QUOTE="DJ Fergus, post: 1764810, member: 93895"] As far as break in, it's been a while since I've had a factory barrel. You are trying to break it in, hoping that it will reduce copper fouling in the long run and level out. Also you are smoothing out where the reamer cut the throat into the rifling upon first several shots. But it's a toss up with some factory barrels cause they can just keep on fouling. I'm my opinion, higher velocity cartridges can be worse about copper fouling. A factory 270 wsm I had was so bad that it was only good for about 30 shots or so before I had to clean it again to get Tight groups. But break in when done with care won't hurt anything. 6.5 creedmoor should not be as heavy of a fouling round as a 270 wsm. Being as you are new to reloading, I would break it in with cheap factory ammo. When you clean it, it will probably take 3 more shots off a clean barrel for you velocity to stabilize. Long story made short, your barrel is probably going to speed up after about 100 rounds from being a new barrel. If you find a load before that, you may have to adjust it down afterwards. 6.5 creedmoor is a great cartridge to start reloading for. [/QUOTE]
