Primer intensity ratings

[overbore]

As most of us know, primers have varying degrees of brightness or ignition producing flashes depending upon the manufacturer and type with the BR types generally being more consistent and lower intensity. Graf now has a closeout on PMC Large Rifle magnum primers but I have no data on their intensity nor consistency. I plan to use them with Varget and N560 powders. Does anyone have verifiable data to share on these specific primers? With much appreciation. Overbore

Great photos with thanks; now for the $64 dumb question: is the PMC magnum primer the same as the large rifle PMC? Overbore

If you had of asked the same question of the small primers, I could have said the only difference is the thickness of the cup. Concerning the small primers, the priming compound is the same whether it is standard or magnum. On the large primers, to the best of my knowledge, the PMC magnum primers are not the same as the large primers as they are made to ignite magnum loads much as the American counterparts.
Hope this helps,
