Problem: I usually play at 250FPS because that's my usual (indoor) field's limit. I have my gun tuned for 250fps at 4ms dwell / 140PSI.
Went to an outdoor field today and couldn't hit 280 without re-lubing my poppet, upping my dwell by a full point, turning my adjuster in (.5 turns out) and upping my PSI to 160. Totally consistent though, best consistency I've seen so far from my Axe (+/- 5fps).
I was thinking maybe the heat might've caused this, any thoughts?
