What freebore are you running with 180 Bergers in 7WSM? I'll be running a single shot so I am not concerned with coal. Just wanting to know if everyone is going with Dave Kiff's recommendation or if someone has found a spec that works better. I want to get to where the bullet when seated with the bearing surface just ahead of the neck/shoulder junction is .060" off the lands. I don't know what the freebore would be to meet that.
