I still haven't seen anything that says PTG fixed the biggest problem with the factory bolt heads.
Is the I.D. of the rim smaller to better fit/hold brass or is it still way oversized like they are from the factory?
This slop is what causes most people's extraction and ejection issues.

Example: a factory .223 bolt head (0.378") usually measures around 0.390" I.D. while most brass measures around 0.373".
