I'm sure others can give you info closer to your barrel length, but here's my results at 16.5". There are also some "rule of thumb" posts that state you lose 20-30 fps per inch, but IIRC that may vary below a certain length. But this is ballpark:14.5 in barrel looking to keep shots under 350
All of the below were shot today from my T3x cut to 16.5" with a TBAC Ultra 9 (Gen 1) suppressor at around 1100 feet and 35-40 degrees. 10 shots each. All speeds are averages.
