8x57 and 250 gr bullet?

[iroc22]

I've got some 8mm 250 gr bullets I'm thinking about trying in my M98 8x57. Anyone else experiment with these heavy guys? What powders and primers did you use?

A google search brought up 2180 fps from a 24" barrel with 48 grs of AR2209 powder. It's an Aussie powder I've never seen for sale though.

You can substitute H4350, IMR4350, or RL17 for AR2209 - 48.0 grs will be, or close to a full case. I have used H4831, 48.0 grs up to a full case, but velocites will not be as high.

I tried some 220 grain Sierras a few years ago with IMR 4350 powder. I don't remember the charge weight but it was at near maximum. The problem was that the heavy bullets were key-holeing. I swapped the 8x57 for my .270 and got my elk anyway.

Thanks guys. It seems like 200gr bullets really are the ideal bullets for the 8x57 case. I'll see what results I get with the 250gr just for fun

I use the 200 Accubond in my 8x57. I am using a nice load of Vihtavuori N550, for very favorable velocities. I have shot a coule of moose with these bullets, and have yet to recover one. Regards, Eagleye.

I have not had any problems with 220gr Sierras at 2475 fps.

I would definitely try the 250's and see if they work.
