Ken, if there were no product liability claims, there would be no consequences to questionable data. Furthermore, many knowledgeable reloaders push beyond �published� maximums with no detrimental effects every day. Granted pressure barrels have shed a lot of light on what is happening in the chamber, but published loads must be safe for ALL barrels, in ALL conditions. This is not do to the philanthropic nature of powder manufacturers, rather, this is due to the consequences if they make a mistake.

<br>If you were to attempt to publish a reloading book rather than your most beneficial cartridge design book, you would be swimming in legal red tape to a point where you would give up. The legal consequences are just too great if someone got hurt.
