That is true in the 308, but it is NOT TRUE in the 223.
Dr. Denton Bramwell did a series of experiments on Hodgdon's "Extreme" powders.
They are LESS sensitive than some in the cartridge that they were designed for. They are no different, or WORSE than others, when used in a case they(the extreme properties) were NOT designed for.
Specifically to the question of RL-15 Vs. Varget.
The fact that they may or may not be close in BR is purely coincidence, as they come from different places and companies.
Varget is made in Austrailia. That is from the ADI plant, who is owned by Thales, a French Defense contractor.
RL-15 is made in Sweden. Is part of the Eurenco layer, of Groupe SNPE; A French state-owned conglomerate.
