Here is a snapshot of an example video I am trying to make showing some virtual pressure curve comparisons for the 44-40 from Winchester Super-X hunting loads to Lyman's 49th WHV loads. I think this will prove at least that the tests are consistent and reliable enough to discuss.
The 44-40 website has been updated by adding the Pressure Trace Video Page
