Yeah, both of us did!
I spent considerable time "experimenting" with Charlie and his Pressure Trace when he was in Texas. Was also lucky enough to spend some time with Western Powders' piezo setup in Miles City--and have visited other pressure labs of bullet companies and one major American ammunition company.
They all provided lots of information, including things not described in manuals.....
Last time I saw John Linebaugh we talked and looked at numbers from Western Powders.
I don’t show them to folks much. Just eye openers.
And that’s in a 500L……..same bullet weight and velocity……..except one was 35k psi…..one was 80k
John loved the study of pressure and velocity. Moving out there and looking forward to reading in his library.
Precision Shooting is another pleasant read.
Thank you for this thread.
