458 Lott load data for 300-350 gr jacketed bullets

[ssj@ms.metrocast.net]

I would like to use 300-350 gr jacket bullets in my custom 458 Lott. Can I use the published data for the 458 Win Mag with these bullets?

Yes. You will just have a little less pressure and speed.

Much appreciated. One reply on the reloading forum suggests the Hornady 7th edition for data for the jacketed 350 gr bullet for both 458 Lott and 458 Win Mag.
