If Mr. Newberry thinks the speed of sound is 18.000f.p.s, then his information is not very creditable. If it’s a typo, then it still doesn’t speak well of his creditability. In addition, just because you can make a common phrase into an acronym, does not mean its plagiarism for another to use that acronym. The phrase Optimal Charge Weight or OCW cannot be considered intellectual property, because it is a phrase that has been used commonly for decades in reference to metallic cartridges and their reloading. The man thinks very highly of himself to think it is, so once again I have to question his creditably. I agree smoke and mirrors, or to borrow from another’s quote; if you cannot dazzle them with brilliance, dazzle them with BS.
