300 WSM Quickload Query

[GoferDog]

Gday guys, would like to know how much H4340 it will take to slow a 200 grain Berger down to 2700fps? If anyone has QL or previous experience that would be great.
That is the only powder that can be had at the moment.
This is a single shot rifle, throated appropriately.
28 inch bbl
Norma brass
Federal Primers
Thanks in advance

Do you mean H4350? And which 200 gr Berger - they make several?

You actually need the exact bullet since they often take up different space.

You need the Overall Length which in connection with the bullet, determines how much space is left in the case.

H4350, 200 grain berger hybrid, 215M, Norma
60 grains was 2710 fps shot fine.
63.6 grains was 2840 and was AMAZING

200-20x, thankyou

Sorry 4350 is correct

Here's a QL print for you. You didn't spec COAL, which very much affects seating depth, which then affects pressure and velocity. But you can get an idea from the the QL default for that bullet.

Likewise, the internal capacity of the case makes a big difference. For a more refined look, especially if you were nearing maximum pressure, you'd want to measure several samples and input those into QL. But, again, the QL default will hopefully give you an idea.

Good luck!
