AR Seating Depth

[hunter24605]

When fine tuning your AR loads (223) do you find accuracy improves seating closer to or further from the lands? Or is it more rifle specific as to the preference of length?
Thanks.

Are you single loading? I can't get anywhere near the lands and still fit in the mag.

No, feeding from the mag..Just curious about depth changes.
