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, lot to lot variation,
manufacture date, 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 extracted from Western Powders burnrate chart, from their V7 Load Manual. You can visit Western Powder's web site at: http://www.ramshot.com.

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.
