The 2016 Hodgson Annual Manual lists a number of loads for the 7×57 Mauser using Windows 760. However, they don't give any data for a154 grain bullet.For a 150 grain bullet they give a starting load of 42.0 and a max of 44.5 grains.For a 160 grainer they give 40.0 as a start and 42.5 max. This can be used to get you started.

Wow! Any chance for pictures of that rifle?

IMO: Your powder is one or 2 steps too fast. All the loads I can find are for Norma powders. Not surprising. 7x57 R @ www.reloadersnest.com

Do you have to use W760?

Because the 7x57R has a lower pressure limit than the 7x57, and because you aren't likely to find 7x57R data from an American source, I believe you would be wise to seek out a European data source. Vihtavuori and Norma reloading manuals are not difficult to obtain. Vihtavuori data can be had online. Here is an example:

7 x 57R - Rifle reloading - Reloading Data - Vihtavuori


That doesn't solve your problem of finding data for W760 in your rifle, but I doubt very seriously such data exists at all. Here is a discussion of a similar issue that may help you to find your way:
