H50BMG in 257 WBY

[338wea]

As the title say I am looking for some start stop spots for loading my 257 WBY with H50BMG, I have already asked Hodgdon and they said that they had no data for that combination and that the case was too small

Most likely if Hodgdon said is wasnt a suitable powder.... Its not.
H50bmg is quite a bit slower than the typical suitable powders.

I read a thread where a handful of people said that they had used it, I was considering it because it's a lot more common around home than everything else
Have some rl26 but my dad is hording it for his 6.5PRC

Interesting..maybe someone with quick load can source out a charge....from everything I see it's way to slow and even if its usable it will not likely give you the best performance.

Quickload data says at 105% case capacity, it will get 3176 FPS with 54,708 PSI pressure.
This is with a Hornady interlock HP.
However it is a not data from actual testinh and i have seen duscreotincies in the liad dara on Quickload .
Their load book shows two powders that will get 3,200FPS.
H1000 and H4831.
50BMG is a very dirty powder and does not measure well, but if ya got it, use it!
