I've been running a 50 degree rubber in my 330FPS rifle for the past year,about 20,000-ish rounds judging by the amount of empty bottles. No hints at performance decrease. I'd say 50-60 degrees should be grand. Most stock ones are about 60 if I remember correctly.so what degrees would i need for a 340fps rifle?
