.38spl Gel Block Tests

A max book load of Power Pistol with a Hornady 110gr XTP bullet only yields about 70% case volume fill. Potentially, the roughly 30% air space can lead to the primer flashing across the top of the powder to create uneven burn or even accelerated burn and pressure spikes. This is not an issue with other powders that have a higher % case volume fill characteristic. One solution that a viewer reminded be about in the comments on a previous video, was using an inert filler to eliminate the extra air space and hold the powder down against the flash hole. He recommended using drying lint, so that's what I'm testing in this video! The results were a complete surprise to me though, watch to see the results! Chrono data pics at the end of the video

Just doing a little trial to see if the extra cylinder length on a .357mag revolver has any velocity loss when shooting .38spl loads.

NOTE!! This load is at or near +P or higher velocities. As always, decrease all loads and work back up for safe pressures in your particular fire arm. Which bullet is best for running in a revolver and carbine rifle combo?? 1 of several handload bullets that I'll be doing similar testing with over the next several weeks. A look at velocity, expansion, weight retention and penetration in the Clear Ballistics 10% ballistic gel block with 5 different barrel lengths! Spreadsheet with data and pics near the end of the video!

Update, I had a copy/paste error on my spreadsheet in the weight retention column. Please disregard those data points.
