Was given several Lbs of WW760. Need loads for 300 win,338 win and 30-30 win if this powder is suitable for these three.

Yes WW 760 works in all 3. It’s not a great choice for the 30-30 but will work in a pinch.

Check it out for yourself at Hodgdon's website.

excellent powder.. great for the 257 bob!

WW 760 is the same spec powder as H-414. To the extent you see variations in loading data from the same source between the two powders it is the result of different powder batches.

WW 760 is a double-based ball powder and thus acts a little differently from single-based stick powders. But in terms of burning rate, it is very close to IMR 4350. The applications for one fit those of the other, meaning that it is a very good match for the .338, is useful in the .300 Win with the lighter bullets (under 165 grain), and is a tad slow for the .30-30 but will provide acceptable velocities.
