I have some W780.I compared my velocity between Reloader 22 and the W780 loaded the same in my 7STW.The velocity difference was about 20-30fps slower than the Reloader 22,which is about exactly the same as what I would get with IMR7828.My rifle grouped well with it,in fact I was getting the same point of impact with both powders.

I have a Sierra loading manual from 1971 and some of the load data lists 780BR. If you can be more specific as to your intended use, there may be a load that is useful to you.

Winchester 780BR and Winchester 780 Supreme are not the same powders.See #130 on the burnrate chart. ![[Linked Image from i.postimg.cc]](https://i.postimg.cc/QCRZk9fw/burnratecolor.png)

I have some, don’t use it as it’s not that clean and I have better powder. But, in a time of shortage it will work.
