I am trying to find data for this powder in for my 257, has anyone been trying it?
Mostly looking for the most velocity out of a 100 or 110 grain bullet.

Check with the powder manufacturer's  and the bullet maker's  sites for start loads.   :)

Below is link to an article where the author gives his pet load for the 257 weatherby and 100V. I have gone out and purchased the components for this handload myself and will give it a try soon. he also shows a pic of the target he fired using the load recipe he provided. The only thing he did not mention was COL of the round, but that is no big deal, just start long and work back in length.

That was a good article about the .257 Here is a link to Barnes data that should work for you also if the Hybrid 100V doesn't work for you.http://www.barnesbullets.com/files/2014/11/257WeatherbyMagnum.pdf

I was very impressed with the actual fps of the 80gr TTSX. Even if you are a heavy for cal type of guy,it should be considered.
Sorry... Yesterday was the last and final day for any and all complaints whatsoever.

I try to avoid temptation unless I can't resist it.

Everyone has a photographic memory.Some just don't have film.

I used the Barnes data for my 2506 at their max load of 100v with the 80gr ttsx and am getting 3750fps and 1/2 in groups. And that’s with a 24” barrel.
