...just a couple of observations based on the images:
(1) the PF bolt has longer length lugs than the Aero.
(2) Original bolt's lugs peening/mushrooming can be (a) excessive bolt thrust during firing or (b) improper hardening of the metal.
(3) In the side-by-side image, the PF extractor appears to be "shorter", the front edge slightly behind edge of bolt's leading edge, which could impact groove that case rim sits in.
(4) Images measuring pin to bolt face relationship may be misleading, same measurement to rim groove's front/rear edges would provide more pertinent info as to how it affects ejection. The pin hole locations would have more affect on the pivot point and attendant leverage pressure of extractors grip on rim.
I would suggest measuring the bolt face depth cut to ensure what type of bolt it is, Type 1 or Type 2.
