Has anyone used Viht N540 for .308?

Particularly with 150grn sierra pro hunter.

Have had a look on the viht app and this actual bullet isnt listed and it does give data for the spbt version from sierra.
Max and mins across the other vary quite alot. So just wanting to ask what other has used or found a starting point.

Cheers
 
540 is highly suitable for 308win and I use it in fairly pokey loads which are suitable in those firearms, and of course may not be in yours, so no free recipes.

The sierra data used to list it.

Using the data for sierra HPBT 150gn will be a good guide.

Work up to the desired fps, looking for pressure signs. A mild load for hunting is fine, less recoil and you wont wear out cases.
