I recently built an AR, using a RRA 20" bull varmint barrel with Wylde chamber. Leade is much shorter than with my other .223s. Have to load @ 2.220" or shorter, or I'm into the lands, with 55gr. bullets.

Also recently built an AR, using M4 YHM chrome-lined barrel. Glad I used the old Stoney Point tool to determine length to the lands. Again, much shorter than with other .223s.
