If your engagements average over 45M then run at least 0.32
Gas dependant you can run upto 330 FPS which gives a decently fast BB flight time.
Heavier than 0.32, ie 0.36, will eek out the long range accuracy even further and negate cross winds.
If you regularly play at field that allow 350-360 FPS then consider getting a Prommy 6.03 barrel, this will boost the FPS nicely without negatively effecting any of the TM magic, you’ll also get a little more gas mileage
If you are going to run ASG, then use Devil’s, they are higher grade.
If you look back historically it’s only a matter of time before cheap BBs fook your nozzle.
