Thread: An Odd question...8.15x46R anybody?

  1. #1

    An Odd question...8.15x46R anybody?

    Does anyone shoot this caliber?? I'm looking for the diameter of the original bullets loaded in this cartridge. Info in the US is skewed: I get data that lists bullets as small as .316" yet some sources list cast bullets for a .338 caliber. Whether or not you shoot the cartridge, if you have some data on factory bullet diameter I'd appreciate it. My Mauser rifle has a seven groove barrel so it's hard to measure, but I come out with .318" as best as I can recon. I can't see what a .338" bullet would do to it. Adding to the puzzle is the fact that Hornady sells FL dies for this cartridge with a .337" expander!! (??) ~Muir

    I'm not familiar with this cartridge but 8.15mm is 0.321" so that has to be a good starting point! Googling around I found this:

    I have a 1898 Mauser in 8.15x46R. I make the brass from 30-30. I am still playing with mine and must confess to not having devoted a lot of effort towards it over the last few years.

    NEI used to list a 190 grain bullet for it. I have resized 170 grn NEI and LBT bullets for the 32 Winchester/ 32-40 down to .320" with fair results.
    I'm using Meister 170 grain .32-40 bullets (.321 diameter) that I size down to .318, and give them an "overcoat" of Lee liquid Alox lube.
    I also have a Haenel Aydt in this caliber. I use the 170 gr. Meister bullets, or a bullet I cast from an old Ideal mold for my .32-40, which weighs about 185 grains as cast. Both work well, although the 170 seems to be a little more accurate with this gun.
    Hope that helps,

    Cartridges of the World by Frank Barnes briefly mentions the 8.15X46R with 190gr bullet [ Lyman No:- 338237 ] , 23grs of 3031 powder for a muzzle velocity of 1500 F.P.S. and energy of 956 Foot Pounds .

    Thanks for the replies. My rifle likes .320" bullets but as you can see from the quote from "Cartridges of the World" the bullet listed is from a .338" mold. I believe that Barne's data was borrowed a bit as I've seen this .338 diameter pop up all across the Web. I know that these rifles have groove diameters from .316" to .323" but where they came up with .338" is beyond me. Another quirk in the Barnes data is that the Serviceman's Rifle load is a 165 grain bullet... at least from what I've read. It's a puzzle.~Mir

    According the the tables printed in Steeds book on commercial Sporting Mausers the bore size is 7.70mm and groove size 8.05mm whilse the bore size of the 7.92mm (8x57JS) is 7.85mm and groove size is 8.1mm. I hope I read the tables correctly as it's all in German hope that helps a bit.

    It does. Thanks, BH. I'd still like to see what bullet diameter of commercially loaded ammunition was. I guess it doesn't matter as .318 to .320 will work in my chamber and throat. It's just a matter of curiosity for me.~Muir

    Muir, have no clue of this cartridge, but my clever book mentions that this round was designed for target use.
    The company Haendler and Naterman make bullets, apparently in different diameters so that one can choose something
    that'll fit the barrel. Listed is also a Hornady bullet, FP (3210) 170gr
    Bullet diameter is 8.38mm ( 8.09mm / .318)
    They mention that the max diameter of 8.38 should only be used with lead bullets. One should check the barrel for jacket bullets closer to 8.09mm / .318"

    Barrel. diameter 7.6mm / 8.03mm
    twist 360mm. COL 62.3mm
    Hornet powders seem to work well.

    If you want I can post the load data.

    Edi: I always appreciate load data. I wonder if that 8.38mm figure got bustardized in print to .338 inches.

    You're right. It is generally a target cartridge but hunting loads were made in Europe. My rifle is a club rifle of the "Serviceman's Rifle" ('Wehrmanngewehr'??) style Model 98 Mauser single shot with the sight elevator marked for 100M and 200M shooting. It has an interesting mark engraved on the receiver ring. It is a large "S" over lapped with two smaller "A"'s. I'd love to know what that means but I have a feeling it is the owners initials or the initials of the shooting club.

    Ballistically, it is about like our 32-40 cartridge which also was a target round in the 1890's and made it to the field due to popular demand. It is minimal for deer but many deer have fallen to it. I'm certain the 8,15x46R has done likewise.~Muir

    Hi Muir, very interesting. You seem to have one of the "Wehrmansbuechsen" which the book explains were used as pre military shooting training in ww1.
    Try take a pic of the rife and SAA... I could get some info on it off a german forum.

    Thanks, Edi! Great Data!

    I was certain that the rifles were post WWI due to the Treaty but I'll take your word for it. My German is non existent! I'll get off a photo of that mark this weekend. Thanks again! ~Muir
