.375 2 1/2" Barrel dimensions

Hi all, I'm looking for some barrel dimensions for the Lee Speed .375 x 2 1/2" if there is anyone out there with one. A friend is looking to have a CNC programme written for a barrel with integral rib. He has a barrel but it has been chopped back a few inches, so what we would like is the barrel length for any .375 x 2 1/2" Lee Speeds and also the muzzle diameter. With this information he believes he can extrapolate the remaining dimensions from what he has.
Hopefully it will work out well as I have committed to one for a BSA action I have laying around.
So if anyone could help it would really be greatly appreciated.
Regards

25 to 26 inches IIRC . Ive had the barrel for my project profiled to the 303 British H dimensions as I could not find any information on profile measurments . I think a heavier barrel is apropriate for this calibre.

.....I assume the numbers on the right are inches from the muzzle ??

Kynoch,

Thanks for posting the details. I have a question myself; is your quoted barrel length of 25" measured from the bolt face, or where the barrel butts up to the receiver rings front face (ie excluding tenon length)?
