Pre-Threaded M98 Lothar Walther barrels.
      #115758 - 28/09/08 07:38 PM

Was wondering, how well do factory pre-threaded Lothar Walther barrels fit M98 mauser actions?
can I expect a good close/firm no wobble fit?
I know LW workmanship & tolerance are very high quality, but are LR-M98 mauser actions reasonably consistent in their barrel tention thread tolerance?

FWIW as I understand they are cut to standard Mauser thread and angle 55 vs 60 or maybe other way around; not BSW.

Gentlemen,

thank you for the friendly words about german quality! (I´m Bavarian...)

I have three hunting rifles made by three different gunsmiths in Munich (cal. 7x57 / 8x64S / 9,3x57) and all three rifles shoot from "very good" to "outstanding"!
To my knowledge, all gunsmiths ordered and used pre-threaded barrels form LW.
I was on the range last Saturday and shot one group at 100m with the 8x64S in one ragged hole of an dia. of measured 16mm /ca. .6" (handload 200grs Accubond / powder R904 / case Sellier&Bellot).
That is outstanding for my shooting skill!

The 7x57 rifle´s precision was also very good with Nosler 140 and 150grs Ballistic Tip and the Sierra 160grs HPBT Gameking and varmint HP bullets. Precision declined between 3500 and 4000 rounds (in 6 years), now the rifle gets a new barrel, also from Walther.

The 9,3 shoots the lighter bullets (RWS 225grs Doppelkern, 232grs Norma PPC) and the 270grs Speer RN good (regularly under 25mm/4 shots), but the optic is max. 6power and I can not see a small target clear. My opinion: Rifle shoots beautiful but shooter skill is lacking...

I have not answered you question about thread fitting, but the results for shooting LW barrels are convincing.

I would recommend: Try it!

best regards & good shooting!
Rolf

Mauser threads are 55 degree. Starman you don't give your location, it would help,. If you are in the US you need to be carefull if the rifle has previously had a replacment barrel fitted in the states as it is common practice to chase the threads to 60 degrees.

I would suggest that you take a half circle wax casting and check the angle if this is the case before you order.
It may not make a lot of difference if you nip the barrel up slightly over tight (100 Lbsft.)

A pre threaded barrel is not necessarily a spin on fit, you need to make sure that it bottoms on both the primary and secondary shoulder evenly.
As long as you spot that in right and torque it up. then you will get a no wobble fit irrispective of a little thread tollerence.

Regards
