Re: Bergers in 308
The chamber in a factory 700P is very long, Bergers tend to like up close or touching the lands. I shoot Berger 185 VLD's but have a custom Palma chamber cut just for them. I am .004 off the lands. Factory ammo would be into the lands .006=/-, if I shot any.
Take your time and really work testing OAL with Berger loads, keep at least the diameter of the bullet (.308) inside the case however and adjust neck tension accordingly. And in a factory chamber, if you have a detachable mag forget about mag length.
