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.'

The barrel is already as short as it can be.

Would people please stop saying this? The barrel is 18.5" long, which is the limit for a centerfire semi to remain non-restricted (actually the limit is 470mm). Since the Enfield is a manual action the barrel can be cut to 457mm (17.99") and still remain non-restricted.

In this case that extra 1/2" doesn't offer enough to take a second try if OP screws up the threading the first time, but lets not be spreading BS about the actual legal barrel length limits.

It is valid depending on how it might go (hopefully it will turn out well). I think he's gotten some good info in the replies, though. If thought of as a lesson in advanced gunsmithing, it's not a waste of time and money. He can always sell specialized tooling at the end.

It'd be simpler to just use all the same tooling and just directly thread the barrel. Anyone who can do the stuff you talk about, can also just thread the barrel.
