[QUOTE="Dangermouse, post: 2981718, member: 76749"] Found it! Some (one result) of Denton Bramwell's systematic research can be found here: [URL]https://www.firearmstalk.com/attachments/brumwell-powder-temp-exp1-pdf.158627/[/URL] Which is enlightening, even though the name appears to be misspelled (as I also did above). Another series of systematic tests for the 44-40 cartridge can be found here. See: [URL unfurl="true"]https://sites.google.com/view/44winchester/chasing-the-44-40/ballistics-handloading/pressure-testing[/URL] This is what I mean when I say "systematic." A lot of data is collected and used to make inferences about the subject at hand. That site also identifies "RSI" in the proper context. RSI = Recreational Software, Inc. Further, [URL]http://kwk.us/pressures.html[/URL] contains a direct reference to the Bramwell article in Varmint Hunter magazine: [LIST] [*]In 2005, Recreational Software, maker of Pressure Trace, was keeping a copy of an [URL='http://www.shootingsoftware.com/ftp/psicuparticle2.pdf']article[/URL] by Denton Bramwell, originally published in [I]Varmint Hunter[/I] magazine. In this article, he shows that CUP and piezo pressure measurements are well correlated statistically, and he offers some approximate conversion formulas (see below). His CIP conversion formula was used for those cartridges for which I had the crusher value but not the piezo, and these entries are marked [B]*[/B] above.

A site, [URL='http://www.shootingsoftware.com']www.shootingsoftware.com[/URL], where the article link, [URL]https://www.shootingsoftware.com/ftp/psicuparticle2.pdf[/URL], is meant to be, does not open. Does anyone have a copy of this article they are willing to post or post a link to it? It will be appreciated. Here is another site with useful links on this subject: [URL]https://www.wlcastleman.com/equip/shoot/index.html[/URL], which contains deeper links to several systematic results.
