.375 2 1/2" Barrel dimensions
      #298102 - 29/03/17 04:39 PM

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.

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)?

Do you mean on the left ?

I can measure my 375ex Speeder to at the same places & report if you like ?
