having had to go through this exam I can tell you the common denominator between the rifles you mentioned and the ones with no issues are the CRF function.
Folks can say what they want about the PF CRF debate, but it's exams like this shot by very experienced shooters under stress fire that see the cream rise to the top.
Mauser made a rifle to prevent panic fire jamming issues. It worked for the military and it still works for Professional hunters today. Regardless of cartridge choice the rifle should be strongly considered when serious about a DG tool.
