I just got a model 98 8mm given to me with 2 boxes of shells (170g rem and winchester). I will soot it today and chronograph, I was just wondering if anyone had a good starting load so I can workup. Does anyone know how to tell where it was manufactured, from what I see there are 3 matching serial #s (action,floorplate and bolt) It does have 2 stamps on it which look like a bird with a circle in it's talons.
I will report back with the range data later. Thanks

Normally I'd recommend the Hodgdon website for loading data but I haven't been able to access their data for a week now and they haven't returned emails either.

H-414 would be my starting powder and bullets from 170 to 200 grains

8X57 Mauser data from Hodgdon site, it just worked OK for me Vapodog so worth checking again:

Thank you for all that info.

Rem 170g rn chrono @ 2350 average
Win 170g sp chrono @ 2400 average and more accurate about 1 1/2 in groups.

I think it'll shoot much better with a good reload.

Thanks again for the info.

There are various mauser collector sites on the web that can point you in the right direction to find more info on your rifle. Being such a popular rifle over such a long time, you may find that it's impossible to pinpoint your rifle's exact date and place of manufacture. Many have been re-arsenaled and exported until they've lost all identity.
