EMC2Requesting Pressure Calculation .44Mag
I don't know if this is an acceptable practice on this forum, but I was hoping someone with Quickload or similar software cold punch in some numbers for me the next time they're using the program?
.44 Rem Mag
250gr LFN Gas Check BHN Hardness 21
Federal Brass (SAAMI size Specs)
COAL 1.710
CCI 350 Large Pistol Magnum Primer
Moderate crimp
17.5gr Alliant 2400
Thanks for any help you can provide.

tnekkccWith the added length of the cylinder the barrel would figure at 8.3", 1,246 fps, 19,979 psi.
With 6.5" of barrel it would be 1,157 fps, but that would be wrong.
