[QUOTE="brentc, post: 987644, member: 16938"] ASL = Above Sea Level The lands are where your rifling starts in your rifle's chamber. We use the lands as a starting point for seating depth tuning. When someone says they are .050 off the lands it means that they have determined where the lands are for that particular bullet and have seated the bullet to jump .050 to the rifling when the round is fired. We use seating depth as one of the tuning methods to time the bullet's exit from the muzzle. In your instance with a Tikka. Load your rounds to magazine length and work back from there by seating the bullet further into the case in .020 increments to tune your load. [/QUOTE]
