Thread: Making a magazine, just for the fun of it

Keep at it! It is looking good. You have discovered one of the often overlooked facets of good firearm design. The humble and simple-looking successful sheet-steel magazine is actually a very tricky item to design and manufacture, not only in the design but also in the grade of steel that can be readily formed but still keep strength in the thin feed lips. I would concur that you will get much better results with a double-stack/single-feed system, as the blunt nose of the .410 cartridge will present real problems otherwise.
