Clark33 - I wouldn't be too discouraged that you cannot seat your 140AB's close to the lands. Although it's true that many rifles shoot well with minimal freebore it's not the only way. It's very common for mag length to limit OAL to something less than MAX. This is way many shooters install an extended mag box such as a Wyatts to allow to extended seating depths.
Here's a recent example from one of my experiences. I wanted to try the new hornady 162 ELD-X in my Kimber Montana 280AI. The mag would only accomodate rounds loaded to a COAL that was 0.050 less than MAX. No worries. I loaded some at 0.055 to give a little margin, some at 0.070 and 0.100 just for kicks. As I fired these off through the chrono my groups improved and ES reduced with each increment in jump. I settled on the 0.100 seating depth which gave nearly half MOA accuracy and single digit ES. So seat those 140ABs at several depths and see what happens. You might be pleasantly suprised.
