[QUOTE="CatShooter, post: 138850, member: 7"] [ QUOTE ] Did you ever consider that the military loads use a cooler burning propelent to avoid excessive heat in their rappid fire barrels. Military lead alloy may also contain more tin thus making it withstand higher temps. With your extensive background I would think you would consider all the variables. [/ QUOTE ] I do consider all the variables. Military ammo is loaded with the same powders that we use, but they come in bulk (boxcar loads). The military 30-06 was loaded with IMR 4895, a standard powder. In fact the entire reloading industry was started when 55 gallon drums of IMR 4895 hit the surplus markets after WW2. (It was about 4 cents a pound in drums) The military powder equivalents these days are W750 Bulk - almost exactly the same speed (and temperature as IMR4895). There are no cold burning powders. If you shoot mil-surp 7.62 NATO, you will bind that it heats up the barrel just as fast as standard loads. . [/QUOTE]
