Thanks Frank!
So what I have is an AR-15 with the gas port in the pistol position. Tracer bullets are right at 150 grain.
Would you say that 8.5 grains of H110 in this setup would be a safe place to start? I am not too concerned about being subsonic, as these are just for fun. I just want to make sure:
A. The bullet gets out of the tube.
B. I don't over gas my subsonic-tuned AR upper.
Thanks again!
