Ed, not really sure what your first statement means. I also contacted Mr. Roster years ago and his excuse was " as long as shell manufactures say not to use their loads in Damascus barrel guns " that he was going to take the same stand. I pointed out to him pressure is pressure whether from a nitro load or BP load and maybe it was just cover your a$$ legal jumbo on the side of the box but he wouldn't budge. I quite reading anything he had to write.
