Reloading the 300 whisper/fireball
Their are a few of us that have done quite a bit of testing and I've found that 1680 works the best for me. Cycles every time, locks the bolt back and I didn't have to move the gas port or lighten the springs.
Here is an old video with a load .. BTW this load works the gun suppressor or not ..
