What twist is your barrel? Your twist rate (along with throat length) will determine if your bullets (or what bullets) can be loaded longer than what will fit in your mag (to reach the lands). I believe only the heavier bullets can be loaded long enough to reach the lands. For a Armalite AR15 I would load to fit in the mag unless your rifle is a varmint barreled rifle and you want to shoot long distance. I've got an RRA varminter with a 1/8 twist and it does real well with 69gr SMK's loaded to fit in the mag at least to 300 yards (farthest I've shot these).

Here are a couple links you might find interesting -
