Not sure your logic is 100% correct. If the "big caliber" crew already uses premium bullets and draw the line at 7mag then #3 is not necessarily correct and anyone who disagrees with the conclusioin of #3 does not have a major inconsistancy.
Now if #1 read the "big caliber" crew who uses the regular Corelokts draw the line on elk at 7mag, then your logical progression may in fact hold true.
