Measurements

I didn't want them to get lost in the earlier discussion...

Barrel diameter measured approximately where the COAL would be: 0.733"
Muzzle measured just behind the front sight: 0.571" (I *think* the muzzle is turned down for the sight base.)
Near as I can tell, it's a straight taper from one point to the other.

The bore is a bit of a problem as there are 5 grooves and lands. I used a swaged Hornady(?) .32 SWC, the kind with the 'knurling' and dry lube. It measured 0.313" before being driven through and the grooves look like they barely engraved the knurling. My suspicion is the actual bore must be pretty close to 0.313".

Over on Gunboards, in the Lee-Enfield sub-forum, there's a discussion about British specs for bore and groove. There's also some Anglophiles who insist that the Brits would never have built anything other than to the letter of those specs. I'll see if I can ferret out that discussion.

Oh yes, the front and rear sight bases are soldered on and can be heated and removed. On mine, there is a ring which has a threaded boss and is used for forearm attachment (I believe). It's loose but can't get away due to the sights.
