Information regarding rifle

Congratulations on your new rifle. You need a better gunsmith . That gunstock work sure needs improvement. What size are the scope holes, look larger than 6-48 to me.?
All the best.

Thanks shooter50, yes the gunstock need some work.

Congratulations on your purchase. These rifles were built to last for ever. Are you planning to use IOF 0.315 ammunition for it?

Thanks Chengy, no we are not going to use IOF 0.315 ammunition.

Thank you HasnainQureshi21.

That is a Portuguese 937a
Also should have left it in original condition
You ruined it.

Those pictures were sent by previous owner. If you have seen the condition while we were buying it was worse, the whole stock was painted by oil paint. We cleaned it and repolished the stock.

Nope. He cant.
All 8mm’s are not the same.
The Germans with their Teutonic precision gave a cartridge its most accurate and relevant designation
8x57
7x57
Etc
The 1st no gave a projectile /bore diameter and the second number was the length of the case- all in mm.

The Poms, with the insatiable Indian and African market between the wars,used some weirdo definitions as firms competed with each other, especially for the big bore club.
E.g Westley Richard's made a .470” ctg- .470 WR,Competitors made a .476. Change the case length and /or shoulder angle etc and there you have it.
A .404 Jeffery uses a .423” projectile in a 73mm case. But is sold as a .404!

Not to be outdone, WR came out with their .425 WR. A rebated rim cartridge which quickly went down the popularity chart for allegedly having failure to feed in the DG scenarios of
Africa, and introducing many wanna be hunters to their maker via elephants, lions, cape buffalo etc. who did not like to be shot!

I revently read its being offered again by WR.


The German version of the .404J is rightly called 10.75x68mm. They use the same dia and weight of projectiles, but are NOT interchangeable.

The 7x57 was relabelled the .275 Rigby, because Post WW 1, they didn't want to be seen making money on a vastly superior enemy (GERMAN) ctg and action (Mauser) for reasons of patriotism ,but found it fit to import the same Mauser actions,rebadge them as Rigby, and sell it at a major price mark up-for the snob value.
As some one said, “you shoot a vastly superior species of animal with a .275 Rigby, as compared to the common 7x57”

For the record, the 1909 Argentinian contract Mauser actions made by DWM in 7.62x54/53mm, is still considered the ne plus ultra of bolt actions.

OP’s rifle may possibly be a Portuguese Mauser Vergueiro for the
6.5x58 ctg. Rebarreled to the commoner 8x57 German ctg.
After WW2, tonnes of captured 8x57 Mausers were rebarreled to 7.62x51 By the fledgling Israeli Armaments companies.

By some unagreed agreement, the common factor in British bores was- the bore to groove difference was 8 thou of an inch.
And designation was the bore dia. Hence .303 Lee enfield. The groove diameter could and did vary from .311 - .316” depending on groove depth and exigencies of war time manufacture. But known the world over as the ‘three nought three’

The Yanks have everything from 8mm Magnum to .325 super short magnums. All 8mm’s
Its the flavour if the month technique.
Only the projectile diameter may be 8mm ( or .323”) , but brass shape ,powder capacity and chambering can vary as per designer’s whims.

The Indian .315( add 8 thou for groove dia and it becomes .323 which converts to 8mm metric) is a direct copy of the WW1 Austro Hungarian Empire service ctg, 8x50mm R, which the Hon Company of Bedpan makers, aka IOFB, found fit to impose on the sheeple because they could rechamber the leftOver , post independence, SMLE actions for this relatively low power round,label it as NP,and sell it to the civilian market. Subliminal servility to the old Colonial masters (?) also reflects in the 100 year old Enfield/webley and scott revolver design.

No competition in a captive market.

The 8x57 is a vastly superior cartridge firing various weights and profiles of projectiles from 150-180gr at upto 2700 fps.
The .315 IOFB is a short stumpy case with a Long RN 244 gr SN projectile. Western reloading data books put the velocity between 1890-2200 fps.
The IOF .315 i pulled apart 35 years ago had cordite. They may have transitioned to smokeless by now?

Hope this is as clear as mud?
But 8x57 Mauser will not chamber a IOFB .315.

yeah ,you’re right.
After typing reams on the itty bitty phone keyboard , I am heart broken , that I could doubt its provenance.

Another ne plus ultra bites the dust !

To make it more clear I am uploading this photo right one is IOF 315/8MM and the left one is 8MM we use.
