Good afternoon, We will soon be receiving a Tactical Rifle M40A5 in .300 Win Mag and need a suppressor for the application. We understand the 30P-1 is rated up to .300 WM but also understand that suppressor volumn may have an impact on sound levels. So we are asking these questions. Which suppressor, the 30P-1 or the 338P-1, would be better, quieter, for the .300 Win Mag? If it is quieter, what are the sound levels or how much quieter is it? In your opinion, would this reduction in sound level be justified by the increased cost?
