Disclaimers: Unlike some, this author would never deliberately claim to have the last word on this matter, or any other. I derived the facts behind the following discussion from decades of experience, while testing hundreds of chamberings, from the 22 Hornet to the 50 Alaskan, with thousands of loadings, using nearly every propellant available in the last 50 years, and in combination with at least 30 distinct primers – since 1985 I have used up the ink in three cartridges for the Oehler 35P printer during such load testing. (Ken Oehler expressed surprise that any individual could do so much testing!) I have experience in several ballistic laboratories testing unusual loads and unique components of various kinds. In my handloading career, I have had serious internal ballistic discussions with the following persons and groups of people: Bill Davis, Elmer Keith, Parker Ackley, Homer Powley, Ellwood Epps and others that many readers would recognize by name and reputation; myriad esteemed handloaders; and practically every ballistician in the trade, This represents a combined group with experience across hundreds of chamberings, thousands of loadings, and millions of rounds. If one could total the extended related experience of these people, it would reach into thousands of years. In general, besides just talking handloading, I have made an effort to ask about and discus the strange and unusual experiences each had known. Moreover, I have gleaned information from various tomes on the subject of internal ballistics (from Krupp onward) and tried to separate wheat from chaff, as it were, which is no easy task. As a scientist, I always strive to make logical deductions, based upon first principles. Nevertheless, despite what some might suggest as significant credentials in this matter, this nimrod makes no claim as to having God's wisdom. Some might suspect that those who claim to have such insight might exaggerate that matter!
