February 14, 2020 Update: This week, I spent most of my time working on machining parts for the CNC router that I am building.  However, I also made a few experimental shotgun slugs that I plan to test in the near future, and started investigating the possibility of forming 350-Legend cases out of spent .223 brass.  I was pleasantly surprised to find that it is relatively easy to expand the neck of a .223 case all the way up to .357 inch diameter.  However, I still need to find out whether the pressure of firing will split the cases or fire-form them to the chamber, and I may need to make myself a better case trimmer, as the necking-up process often produces a rather uneven case mouth.  In any case, this weekend I plan to upload a video about what gear I carry on outdoor expeditions, since that has been requested a few times, most recently in the comments on the video I uploaded about Kane Lake.
