Yes....Al Angerman's article was a follow up to some of the work done by Rick Hornbeck and Creighton Audette. I believe the Angerman article was in '93.
After that article, I tested primers extensively in the big cased .17's, finding some definitive stuff.
Presently, both the 6PPCs and the 30BRs routinely operate in the pressure range that no small rifle primer would have survived back then......
Good shootin' -Al
