I have a AR barreled with the 223 Wylde chamber. I am resizing full length. Military brass with my RCBS 223 Remington dies. The brass is trimmed to length, and with a 55 grain fmj, the book says COAL is 2.20" . So why won't this load go all the way into the chamber of the Wylde, but work perfect in another gun with a 5.56 chamber? I thought is was supposed to be a compromise and work in both? The die is set to just "cam over" on my RCBS press.
