You da man with the plan for the 450-gr TSX.

I have a spare M70 375 just sitting around waiting for a new barrel, it was between that and the 400 h&h but dang are those dies pricey


Yes, that is the one, ".410/404 Jeffery Rimless Nitro Express" aka the .410/404 JRNE aka the ".410 Journey."
It was quite the journey.
Use 404 Jeffery Rimless brass from Norma or Hornady and the 450/400 NE 3-Inch handloading dies from Hornady.
Treat it just like the 400 Whelen by fire-forming with backwards handgun bullets.
Shoulder step may be bigger but it is only about 7.5-degree hemi-angle compared to stronger 23-degree angle on the Whelen.
