It drives me nuts when I cannot nail something down. At Steve Duffy's "JFK Assassination Index" blog, the entry for Chapman refers to "Re Access to Autopsy Materials by Dr. E. Forrest Chapman" as though this is a document. The citation is to "JFK Collection List, pg. 27 (AMKW 65)." AMKW is a three-part collection of documents compiled by indefatigable researcher Anna Marie Kuhns-Walko following the 1992 document release. AMKW 65 would be document 65 in that collection. Discussions in the 1990s say the collection is "marketed commercially by such organizations as JFK/Lancer" and is "easily accessible" - but darned if I can find it.
At the MFF website, I found a reference to the Rockefeller Commission Report that quotes Chapman as saying in a telephone interview that if there were GK shooters they must have been very poor shots because they missed everything. MFF also has the AMKW 65 reference but apparently not the document.
It sounds like Chapman was closely aligned with Cyril Wecht and mostly shared his views. With that, I think I've reached a dead end.
CE 543 FBI FRAZIER
The article about Dr Chapman came from this magazine. I believe this is the predecessor of The New American Magazine
They Killed the President, by Alan Stang (American Opinion, February 1976).pdf (archive.org)

Military primers in military rounds are different in makeup than the civilian market primers. Much harder and designed different. Comparing the row of pictures to CE 543 is really an apples to oranges scenario. At the time we did not have any Western Cartridge cartridges and only used what was available to make the point. The reason for the second row or additional row of pictures was to show individual carcano rifles were not the same as far as how hard the firing pin struck the shell casing primer. The second row is far less dented in.
The best we could do was to use two Terni 1940 M38 rifles but the way these rifles were prepared for the American market was to just put them together and make sure they fired the round and ejected it.
Personally, I can’t believe the FBI missed so much about these shells. Not only did they miss the dished in primer but the Chamber Mark on just 5 of the 6 shells. They had six shells in their possession and noted the chamber mark in the analysis of some of them but not all. It would have been easy to look and see what was in the chamber causing the indentation and maybe did look but did not note it other than to state it about some of them in the analysis. I have wondered if they realized to declare that only two of the shells showed to have been fired would that information have fueled a conspiracy belief with Merriman Smith’s/ Walter Cronkite’s three shot News Bulletin.
A conspiracy is exactly how Dr Chapman and Josiah Thompson viewed the information.
