I have been offered some 30-06 cartridges that appear to be grenade launching cartridges. The guy has two types. One has the normal 5 star crimp and the other has a 6 star crimp. The guy claims that the 6 star crimp is a much stronger cartridge. I can not find any info about a 6 star crimp.

Any Ideas?
