Quietest suppressor you have ever used?

[Fritzcat]

Look on Hornady Web site for the Powder burn rate chart.#9 is45, Lil Gun 48, H110 49, Win 296 50,AA1680 is 54. The slower the powder the more gas energy to cycle the gun. You can look on Sierra site for Whisper loads. I don,t know piston AR. You have to figure how to make it cycle the easiest to use faster powders. I use 9.5 Lil Gun with 220gr Horn RN and Blue Dot for 150gr to 180gr. bullets. I,ll sent you a PM.
