The cartridge is 378 WBY MAG (26" barrel)

LOAD #1

115 gr of IMR 7828

What does quickload say as far as pressures gofor the above?

Now.....1 more question. I have the following load which I have not shot yet. Can Quickload estimate velocity and pressure too? If so how much?

wby brass
fed 215 primer
118 gr of Reloder 25
C.O.A.L. 3.687"
BULLET 270 GR COMBINED TECHNOLOGY FAILSAFE

VELOCITY?????? FPS AT 15'

I can't thank you enough!

Anyone?

Assuming the bullet is 1.215" long, and the barrel is 24" long
load #1 3002 fps, 57 kpsi, 100% case full
Load #2 2885 fps, 48 kpsi, 102% case full

The program is a usually very close on case fill right up to the base of where the bullet will seat in the neck. If Re25 will compress at all, 123.5 gr gives 57 kpsi, 3031 fps, and 107 % case fill.

123 gr of RL 25....scares me even thinking about it!
