I have an old Browning BAR 300 Win Mag.
I've considered FL sizing and COAL and thats just fine. A little shorter than what I would do for a bolt gun and I made sure they were sized completly to feed proper. But what I'm wondering if I need to go higher in charge weight to compensate for gas powered operation.
I just loaded up 40 rounds
165 Nosler Spitzer
Do you think that will be ok? I haven't fired em yet. I looked through two different reloading books but all the test guns were 24" barrel bolt guns.
