Re: bullet seating
You can seat bullets firmly into the lands using starting loads and working up cautiously. As has been mentioned, you will reach maximum pressure before you will by seating just off the lands. You will also likely see better accuracy by jumping the bullets, but every rifle is different. One thing to be wary of...When you seat into the lands and chamber a round, then decide to unload the rifle you can leave the bullet stuck into the lands and when you open the action dump powder all through the action. This makes for a sizeable mess and is no fun (or so I've been told [img]/ubbthreads/images/graemlins/wink.gif[/img]).
