[QUOTE="J E Custom, post: 1982185, member: 2736"] It is common for some factory loads to use proprietary powder charges that we cant get. they will have a set of specifications for there load that the powder manufactures must meet that Is often duplex loads with a binder to keep them in order, or a blend of powders that the powder manufactures can't/won't sell to the public. Before all the powder burn rates that we have today, some experienced re loaders practiced this with great caution. and had certain rules that could not be deviated from for safety. One example I encountered was a load that was impossible to duplicate the velocity at safe pressures . After pulling one of the bullets I found a solid, compressed powder charge that after digging it out It would not go back in the same case in a loose powder form. I still don't know how they cast the powder charge because i have used compressed charges with a drop tube and never seen powder that was this hard and like solid rocket fuel for models. Normally these loads are faster, but no more accurate, unless your barrel likes velocity. Most ammo companies don't want to load these load because of the liability of being shot in poor or older firearms. And this practice is only used On new firearms with new chamberings (Like the 6.5 Creedmoor) because it will be less risk in new firearms, and if the rifle has been re chambered or re barreled, you are on your own.
