Re: What EXACTLY is the Difference...Manuals??
Charges have gone down due to the way they measure the pressure. Older manuals had pressure check via a "copper crusher" or CUP measurement. This pressure was measured based on how much a copper pellet was "crushed". Newer, much more accurate methods of measure have been used over the last 10-15 years. It is an electronic measure and quite accurate. ALSO, pressure measurements will vary from one company to the next because they each use their own test barrels. If one company's barrel is .0001" smaller,(tighter!) that pressure is going to be HIGHER and vice-versa. Also, I have my suspicion that company lawyers are in the equation somewhere. Older manuals will generally have larger powder charges for a given bullet. Sometimes, dramatically so!
