[QUOTE="J E Custom, post: 1797094, member: 2736"] I would also ad this bit of information and let the shooter decide what or if he wants to do. Squib loads can be very dangerous for many reasons and using powder with burn rates not in the cartridge range can be tricky and unforgiving. Case density is very important because ANY space not taken by powder has added oxygen and this oxygen changes the burn rate of that powder. Any fillers. Cornmeal, Dacron wool, Tissue, ETC are porous and have a certain amount of oxygen that is added to the powder (It already has it's own oxygen producing compounds). This is also the reason that 80 to 85% case density is minimum for safe operation. When you use a faster burning powder the whole process is accelerated and can be even more dangerous. If you place powder is a controlled environment it is relatively safe, But if you alter the proportions of all these factors. you create as explosion instead of a controlled burn. and what seems like a safe operation can turn ugly. If you accidentally double charge a 80 to a 100 % case density load all you get is a mess where it runs over and spills out on your bench. But when you make the same mistake with a fast burning powder that could take several charges without filling the case. You will not enjoy the results. Time was, that duplex loading was use by some (Like me) and the problems were many and just not worth the risk. now that we have so many choices in powder burn rates, this practice has gone the way of the dodo bird. Just because something is done buy many, doesn't make it safe. J E CUSTOM [/QUOTE]
