If you cared to do your homework rather than pontificating you would find that most of the gun manufactures advise against using more than 100 grains of loose powder, of any kind, in their 50 caliber guns and have for years. I can only speak to what I have been told by quality control people at CVA and Traditions. I have never had reason to contact Knight or any of the others. CVA states categorically in their manuals to never use more than 100 grains of granular powder , no sabots over 300 or conicals over 400 grains in any of the guns they have marketed. .The chief of quality control at Traditions stated that although their marketing people insist on stating otherwise their bottom line is not to exceed 100 grains. Hodgdon publicly advises never to use more than 100 grains of any of their products, pellets or granular, in any 50 caliber gun no matter who manufactured it.
The fact that West Law, the largest legal data base in the world, has not recorded any litigation concerning a person being injured by a fragmented primer should tell even you that the horse you are beating to death is basically a non issue.
I have taken the time to review close to 100 postings on this forum and seldom have I seen anyone describing using more than 100 grains of powder in speaking of the loads they use in the field or on the range. This says quite a bit to me and should say something to you. You seem to be unaware of the fact members of this forum are intelligent beings who are well aware of the inherit dangers involved in using firearms.
As a psychologist, of some repute, who has been licensed to practice for over 45 years I have noted with interest that rather than attempting to repudiate statements that are opposite to your own conjecture you use the same rhetoric, in different phraseology, rather than proven empirical fact to sustain the position you have taken. Professionally I can only surmise that you made your original posting and have attempted to validate it as a form of self-edification and to question the intelligence of the other members. Unfortunately you have failed at both in my estimation.
P.S. Self proclaimed experts are an anathema to an intelligent mind.
