very strange thread, its 1" - 20 UNEF???
Please how did you demount/disassemble barrel from a breech block, and still dont know how to remove the secure pin which is placed on a left side at the breech block?
Thank you.
I don't know what pin you are talking about.Quote:

look at the pocture https://www.gunboards.com/threads/re...e-1867.183925/, the picture is from Aug 15, 2010, - there is a breech block and the screw (is on the top of left side), and upgraded 89 breech block has insteed this screw a pin, it is almost invisible because it is grinded together with the surface of breech block.
So my question is what is the screw at old breech block(and also what is the pin at the 89 breech block).
Thank you for the picture.

Sorry, I cannot identify your problem and I'm not going to take any more time to figure it out.Quote:

Mira, a screw was used to secure the sliding cartridge extractor on the old 1867 model. When converted to the 8x58R model 89, the screw hole was plugged and the screw head was ground flush with the surface of the action. The updated 89 action used a rotating extractor, which required a new screw located under the forward breech block pin. I have never removed the barrel from a model 89, but I don't believe the ground off screw, or pin needs to be removed to unscrew the barrel.
Bingo, thank you Gewehr-Guy, it is it what I ment.
So nobody knows if I must this plug screw out (pull out) before I start to dismantle breech block and the barrel (from Swedish RB 89)?
If your receiver still has a sliding extractor it must be removedQuote:

You are correct
so the barrel is already pulled out from the breech block and the breech block will be reinforced (very sensible by laser welding) in the near future.
I measured also the barrel bore and it has 7,95-7,96/8,21-8,22, so worn ca.0,05-0,06mm (orig. cal. is .323 so 7,90/8,22).
So my question what the condition is the barrel, (is 0,05mm a lot of wear)?
