Iv been using my AAC Cyclone on both my grendels and haven't noticed any FRP or strange groupings. All my velocities from chrony seem ok. What can are you using? I do have some rifles that show the first round to be lower in velocity, I believe due to the barrel being cold then heating up as shot leading to higher velocities as fired. I have found no difference in this from suppressed to unsuppressed.
