Hoping some kind soul with Quickload might provide me with the following data:
5.56 chamber (223 Wylde would work too)
18" barrel, 1:8 twist
RP brass
77gr SMK @ 2.260" OAL
I'm interested to know the charge weight and velocity for IMR 8208XBR and Varget at 55k and 60k PSI pressure.
And if you're feeling generous this new year:
223AI
22" barrel, 1:7 barrel
Nosler brass
80gr A-Max @ 2.485" OAL
Interested to know charge weight and pressure at 2900fps velocity with IMR 8208XBR.
Many thanks!!!
