I made a few videos of the pressuretrace II results for the 44-40 loads and posted them on youtube. When I went to post them here on Full30 video channel, they were gone from my files…oh joy!
My apologies. Here is the link to youtube. Videos
The 44-40 Google Docs “Pressure” Page has been updated to reflect the 3 new tests 1A, 2A&2B (re-tests for “control”), and test 90. I also updated a few other items by including the 1917 WRA data and highlighting Lyman’s max loads that were previously tested. I will update other items as well as dates etc. the week of the 20th.
There is just too much information for me to repost it all here, especially since there is only a link for photographs.
For those that are somewhat following the progress, I have updated the Pressure Testing page of the 44-40 website with a large selection of test result charts to compare.
The test results prove that early smokeless powders used by Winchester produced less pressures than original black powder loads. They also prove that the 44-40 ballistics was greatly reduced by the 1970’s.
Black powders of today create less pressure than those of the originals and sends the wrong message about pressure comparisons for modern smokeless loads.
