S510 odd chrono results
Posted: Fri Apr 21, 2017 2:01 pm
Afternoon Guys
I have an s510 ultimate sporter, I' bought the rifle new a couple of weeks ago and have put approx 500 pellets through it
Today I had the chance to borrow a mates chrono and decided to do some testing at my local range.
I'm not new to pcp air rifles as I also own a 410 carbine and I'm familiar with power curves etc
I filled the s510 to 190 bar to shoot a 60 shot string over the chrono, and the results were quite strange.
Instead of the numbers increasing and then settling out and then dropping as they do with my s410, they started high and just decreased.
The results as follows
784.1
783.6
783.6
780.6
783.8
782.5
