Nathan FosterRe: 8x57 informationHi Shane, sorry, still a little while away from uploading 8x57 research, am still busy working on the next book.Must be 'day of the 8x57' today as I am working on another today. OK, highland brass is heavy walled so keep that in mind to begin with. Book max may be right on max for you. Use 2206H (H4895) powder. Book max velocities (ADI) are good guidelines. But in very worn rifles (throats), I sometimes have to go two grains over book max to achieve book stated velocities. It is pretty much as simple as that. The potent velocities of 2990fps stated (150gr bullets) are obtainable. The rifle I have been working with here, gave 3087fps during load work which is not uncommon but is very much a maximum load. With 150 grain bullets, it is normal to find accuracy sweet spots at 2900-2950 with relative ease. The 175 grain Sierra comes to life at 2750fps (I was up over 2800fps during load work last week). 200 grain bullets can be driven at around 2500fps. Please use the COAL article on this site, particularly the .308 throating/seating methods. You will need this info when determining seating depths. If you do not have a copy of the ADI manual, you can download it online. The 8x57 really is a wonderful cartridge when loaded to full potential. Will provide more detail with the full article when I am able to upload it. Keep your camera handy Shane, I would appreciate any autopsy photos with factory ammo and hand loads. |

Gert OdendaalRe: 8x57 informationHallo ShaneI just want to confirm the bore diameter of the 8x57 JS is .323 and not .318 as in the old original 8x57I loading a 154gn spitzer bullet? In the .323 bore you can really load to the maximum . I really would like some loading data as well. European hunters use hot loads for the .323 bore 8x57 JS Mauser. Regards Gert Odendaal |

shane beechingRe: 8x57 informationHi GertYes it's .323 diameter. I'm using ADI 2208, just loading up some rounds today using 150gr sierra. I'll post the results we done |

shane beechingRe: 8x57 informationWell, the reloads didn't go to well. Rifle did not like the sierra 150gr bullets. My question is, its a short barrel (16in) and would i be better using heavier bullets. Im unsure of the twist rate.Thanks Shane |

Gregory PerkinsRe: 8x57 informationMy military Yugo and K-98 Mausers with longish 29 inch barrels are mynew hunting toys. one with a Scout scope mounted forward is weighing it close to 11 pounds so it is my favorite reduced recoil gun when shooting 180gr at deer. Lately I am playing with Hornady 125gr .323 bullets at blistering 3220 fps using 57.5 gr of AA2460 powder. Never woulda thought of the Mauser 8mm as a varminter ! Hodgdons new CFE223 powder is giving me an extra 100 fps over H4895 for the 180gr bullets. no doubt my longer barrels are helping with the velocity. Hope that helps. |
