How much space is required between the tips of the bullets and the front wall of an AR Mag. I loaded a couple of my new Nosler 55 G. Varmageddon bullets and there is not much space, however there is some. Is there a required amount of space or just as long as it runs/cycles cleanly its good enough.

This.

There can be issues if it's long enough so the bullet is jammed into the lands, but this usually isn't a problem.

A known standard for match shooters is 2.250" col. This leaves about .020"-.025" of clearance in the magazine.
