Threading a 303 Brit barrel

[OkayShooter]

Personally I love it

Too bad it didnt work for sh!t. Most I ever got was 3 rds to chamber, fire and extract. Very roughly, with alot of pulling back the bolt, to let the back end of the round pop up to align, then close again. Worked fine as a single shot.

I once priced out the CNC warrior style with a pilot, cutter and die, by the time I had it shipped to my door it was comparable to the price of paying a professional on a lathe.

It’s a neat idea, not sure it’s a good idea though.

Can't be done? A split die for a 5/8" or 1/2" thread? The problem would be getting the thread axis co - axial with the bore axis, and the quality of the threads. The barrel is already as short as it can be. Therefore no do overs.

Get someone to turn a hollow bushing to match the exterior taper and with a stepoed hole? Get them to start threads on it.
You'd need to affix the bushing to the muzzle somehow (flank pins) like the way the rear sight base is held onto the #1MkIII? Still, you are running into $$$ but you don't need to ship your action anywhere.

Like the poor dude in 'Falling Down' the job is 'not economically viable.'
