So, in the summer when it was HOT, I got chronoed and it read 780fps @ about 30°. I chronoed yesterday and the 40 shot sweet spot averaged 749 @ 6°.
So is this purely to be expected and down to temperature or do I need to get the gun serviced?
I've been using it for 18 months and it was serviced a year before I bought it and unused till I got it. I shoot an hft comp most Sundays.
