Trying to find some Vihtavuori data for the .257 Weatherby - 115 Ballistic Tips............they have .240 & .270 data listed - but no .257 Weatherby.
Anybody know a starting and max for the N568, or where I can find the data.
I tried to reach out to Vihta - their process for asking...

Thanks for your help in advance. I have two loads, I’ve been shooting for many years with older data that has never caused any issues in either rifle. I’d just like to see what muzzle fps they are generating.
Can someone please run a Quick Load on both of these 2 loads ?
270 Winchester – 150...
First time on the board. I’m sure not what a “Quick Load Data” report is.
Looks like it will give me the load data and the muzzle velocity of that load.
If so, can someone run one for a 257 Weatherby – 24” barrel
110 Grain Accubond
H1000 powder – My current load is 71.7 grains. Not sure what...
