FPS and joule question
So I have a question about my local field all Patriot airsoft with there joule and FPS. So the maximum FPS I can do with a .20BB is 400fps which is also 1.49joules so I run a .30 bb at 315fps at 1.38 joule and refs who Chrono say that is over the limit. Am I wrong or are they wrong. Also all my guns are AEGs
