.405 Winchester load data

I have been working on loads and getting up to 2600 FPS but accuracy was not there. Currently working around 2500 FPS but I think my scope may have went south. Going to switch it out and see what happens.
 
Thanks, guys! I have around 20 fired cases along with 60 factory loads. Waiting on dies and hammers!
I don't have any Norma 201 but will figure out a substitute. Thanks again!
 
Anything in that burn range will work fine. I got the Norma powder during covid era because that was the only powder brand available. It works very well on a number of cartridges. Best groups I had in my Grendel was using it. Plus I still have three pounds of it.
