8x56 MS to 8x57 Mauser any thoughts?
« on: April 24, 2006, 09:21:12 AM »
Can anyone give me any help here?  I have the opportunity to purchase a Mannlicher Schoenauer 1909 carbine in awesome condition for its age.  It was 8 X 56 MS and someone rechambered to 8 X 57 Mauser do you think this is a problem.  We did take the rifle and the owner ran 5 round through it, no problems.  Brass no lumps bumps or shiny spots.  Any thoughts would be appreciated.

The MS rifles are beautifully made of the best materials avaiable,, I don't feel there would be a problem.. If the brass checks out and the primers are nice and round(not flattened) then I see no reason to worry.

To 8MM Mauser?
8x57 mau is .323.
8x56r is .329.
Accuracy is probably going to suffer greatly.
I know that using .323 bullets in an 8x56R
works but it is basically like shooting a smoothbore
because of almost no rifling contact.
How far did they have to set the barrel back
to do the conversion?

  I have a model 1908 Mannlicher-Shcoenauer rifle in 8x56 Mannlicher Schoenauer.
I find it interesting that you have one in 8x57,as mine was at some point stamped "8x57"
  The M1908s are 8x56 in most all cases.
 The Mannlicher Schoenauer cartridge is not the common 8X56R Austro Hungarian service round, it is rimless and very similar to its German cousin using a .323 bullet.
  I shoot mine with cases formed from 8x57, they will not feed through the Schoenauer
rotary magazine until fire formed on the first loading,the precision ground rotary follower is that close.
  I simply neck size the case in a 8x57 die after that. Then the rifle performs flawlessly.
 I suspect that sometime in my rifles life it was taken over international borders, and many countrys require the caliber to be stated on the rifle,and some clerk did not understand the differance between the common Mauser and the proprietary Mannlicher round. 
   Your rifles caliber will save a lot when it comes to brass,I paid 100 dollars for 100
cases some years ago.
            Best Regards,Creosote
