Bob - I'm not sure I'd push to 2,400fps with a 250gr. from the 57mm case. I had 2,200fps to 2,300fps in thought when I typed out my response. I'd certainly go to the 2300fps range + a bit in a M98, but as always, keeping an eye on pressures & presure signs, case appearance, extraction and lastly primers.

Do make the brass fit the respective chambers (if possible) before it's loaded for fireforming. It will last longer due to no stretching when finally formed.

I back off the FL die a bit to make sure I don't push the shoudler back when sizing. I've never had to 'bump' a shoulder as the BR boys continually must. That is due to the REALLY high pressures they generate. The fact that I only have to neck size, should show my loads are usually discrete - as least on the low sideof max, yet I do like to get what the case and action is capable of. That is why my 9.3x62 and .375/06IMP both post better ballistics than 1912 .375 H&H mag ammo. Do be careful, keeping a close eye on the progression of pressures.

We found that moderate to max. .358 Winchester data was useable in the 9.3x57 M96 Huskys. I suspect moderate or middle of the road data will also work OK in the 9x57, with same weight bullets. It gives a place to start. With moderate powders like Varget and H4895, you can start with middle of the road WW .358 data and 200 through 250gr. bullets & loads.
