| 9x57 Brass and Bullets? | Login/Join |

Does anyone presently make properly headstamped brass for the 9x57 (9mm Mauser). If so, where can I get some? As far as bullets go, Hawk makes them, and their 250gr round nose would suit my needs just fine, but it would be nice if I had another option available. I would rather not use .358" bullets if I don't have to. Thanks for any info provided. Matt Matt FISH!!

Huntington shows Horneber 9x57 brass. Not cheap at $53/20 though. | |||

So 9mm does not equal .358? I did not know that. | |||

i'd slug the bbl before i decided on what bullet diameter to use. many 9mm pistols have 357-358 bbls on them. and many rifles are built with a 358 bbl and not the 355. | |||

Regular .358" bullets are likely to work just fine in your 9x57. You'd be surprised how much groove diameter varies in "standard" calibers. Two one-thousands is nothing in terms of a .35" bullet. Lots of folks do just fine with .323" bullets in their J-bore Mausers, which are nominally .318". | |||

Correct....so long as you actually work your loads up in YOUR rifle. Don't start with near max loads from some book (or other loading data) where the author was using .355 bullets. If you don't start low and work up your loads when using .358" bullets in a .355" bore, you MAY get an unanticipated surprise or two....and need to buy some more of that expensive brass. | |||

If you are that concerned about matching bullet diameter and groove diameter, a Lee bullet sizing die is the quick answer. Sizing .358" bullets down to .355" is childs play. However, if .358" bullets pass effortlessly into the mouth of fired cases, there is no reason to take this step. I don't know what your need for "properly" headstamped 9X57 brass is, but I would think that a little careful work with a number stamp and a hammer on the "8" of an 8X57 case would solve the problem for all but the most unreasonable of customs inspectors. By the way, wouldn't "formed" Bertram brass still be headstamped with the caliber of the parent cartridge? | |||

Agreed. I skipped the mention of working up a load for the specific rifle simply because this caution is universal regardless of whether you are using slightly oversized bullets. | |||

I knew you knew that. It wasn't aimed at you. It was aimed at some newbie lurker who might read our posts and just go blindy ahead willy-nilly. I just always toss it in because so many loaders tend to kiss it off. Don't know why so many are always thinking the book max's are not really max. guess its because it doesn't blow their gun up on the first shot. | |||

Thanks for all the info fellas. You have noticed my question regarding makers of Oberdorf style Type "M" bolt handles. One of the rifles on my bucket list is an Oberndorf (or close copy) Type "M" stutzen rifle (Mannlicher) in 9x57. I saw a Mannlicher Schoennaur model 1905 in 9x56 M.S. many years ago and thought that a rig like that would be nice in the Colorado timber. All the research that I've gathered up till now indicated that all 9mm mauser barrels were .356" groove. I was thinking of someday having Dan Pedersen make me up a .356" grooved barrel in the original Mauser Type "M" contour. Looks like .358" groove and bullets might be a good option. There are more practical and modern cartridge options, of course, but I'll stick with what I have in mind. Thanks again for all the good advice. Matt Matt FISH!!

I may just add regarding barrels and internal barrel dimensions: I see the term "wide variation in barrel dimension" thrown about with regularity and that is not true when your rifle and barrel is a genuine Original Oberndorf Mauser. Mauser with typical German Precision and attention to manufacturing detalle lapped their barrels and then measured them prior to final release. In this they had a "no go" standard and if the barrel did not comply it was scrapped. They were very, very particular about this ! I saw the same thing still applied at the modern Sauer Factory in Germany. Some years ago I had good fortune of visiting this factory and saw first hand how they on a floor so clean you could eat off the surfaces produce modern sauer rifles. They had this older dude "the god of gunmaking himself" with the title to go of Master Gunmaker that did the final inspections and shooting of the guns. If it did not comply to the set standard by measurement the gun was turfed! First and foremost: The 9x57 or 9/88 as it is also referred to is not a 9mm (.354) cal but a 9.1mm (.358) The . 354 cal is a American guns scribe assumed fallacy based on a true 9mm cal assumption as in 9mm pistol bullet dimension ! So if your Genuine Oberndorf Mauser is a 9x57 and the barrel is original then the dimension will fall within the following dimenions: Bore = 8.85mm + 0.03mm - 0.02mm Groove = 9.1mm + 0.03mm -0.02mm So the Groove dimension is in fact a .35826772 inch which is why modern cup and core .358 bullets do work in this rifle without problems. The "normalized" dimension for the 9mm / 88 or as we know is 9x57 as adopted by the German Association for Arms and Ammunition Manufacture was decided on a groove dimension of 9.08mm -0.05mm and a bore dimension of 8.83mm - 0.05mm whilst the bullet dimension was normalized at 9.08mm -0.04mm So for the bullet it was .35748 inches whilst the normalized dimension for the groove was set at .35748 inches | |||

I had a J.P. Sauer 9x57 a few years ago that had such a tight chamber that I had to use unfired 8x57 brass resized through 9x57 die before they would chamber in the rifle. This sounds crazy but I had several pieces of once fired 8x57's and even after running them through the 9x57 dies they would not chamber. Additionally I had to order a bullet swagging die and size the .358 bullets down before they would chamber. Once I worked this all out the rifle worked very well with 250 grain bullets. | |||
