Homemade bolt action

DISCLAIMER : reproduce at your own risk. At least, this one should be legal in most countries.

This is about the action, not the gun, so the short smoothbore barrel and shabby magazine shown are only for demonstration. A bolt action is only worthwhile if you have access to properly rifled barrels.
The bolt is rimfire only (using .22 magnum in the video) but can be adapted to centerfire cartridges simply by drilling the firing pin hole in the middle of the bolt face instead of in front of the chambered cartridge's rim. There is also no need for an extractor slot in the breech face with rimless centerfires since the groove the extractor catches can be left sticking out of the chamber.

This action is rear locking. It is simpler but also weaker than frontal locking lugs. With the top of the handle locking alone like in the video, using anything more powerful than a .44 magnum is asking for trouble. If you make a double recess in the stock in order to lock both the bottom and the top of the handle, it should handle rounds up to a 30.06. For example, the Lee-Enfield in .303 is rear locking. Using steel inserts for the handle to lock against is always a good idea, they can spread the blowback over a wider area of wooden stock.

And TEST ANY ACTION YOU MAKE THROUGH AT LEAST 20 ROUNDS WITH A STRING AROUND THE TRIGGER WHILE HIDING BEHIND SOMETHING SOLID. Seriously, not my problem if you blow up half of your face.
