Thanks! Shot 4 more theee shot groups, cleaning between each one. After the clean bore shot, the following 2 shots in each group were cutting holes averaging .236" across the four groups (all shots taken 8 minutes apart). I'm gonna call my break in good (18 shots, cleaning every third shot) as this barrel does not foul AT ALL. It cleans up as easy as any hand lapped match grade barrel I have ever owned. Same load I use in my other Creedmoor, no need for load development on this one. Very impressed with this little rifle.
