Comparative Powder Burning Rates

WARNING! WARNING! WARNING! WARNING! WARNING! WARNING!
The actual burning rate and position on this chart can be drastically altered by many factors including case size,
bullet weight, expansion ratio, operating pressures, etc. Industry tests have shown that a powder's location on
this list can shift by 5 - 6 positions or more depending on conditions. This data was typical under the test
conditions it was developed under but may not be true under your circumstances.

Do not attempt to make powder changes or determine a load based upon this data.

Data based upon the 308 Win. cartridge using all the same lot number Winchester cases, Winchester Large Rifle Primers and Sierra 168 gr. BTHP Match bullets. Note that many ball powders can exhibit unexpected extreme changes in pressure below 35 degrees F and above 105 degrees F, rising pressures 10,000 psi or more at elevated temperatures. Be careful at the temperature extremes! In addition do not use ball powders at very low load densities.

As far as I know all the information presented above is correct and I have attempted to insure that it is. However, I am not responsible for any errors, omissions, or damages resulting from the use or misuse of this information, nor for your doing something stupid with it. (Don't you hate these disclaimers? So do I, but there are people out there who refuse to be responsible for their own actions and who will sue anybody to make a buck.)
