Well I normally would shoot the same pellets washed through a chrono as I would in a comp and use a whole tube of air starting from 200bar until you can see the fps drop off. I've always wondered what people mean when they say "I got 9fps Spread" the whole tube or just 5- 10 shot string. I did my S400 the other day and stopped at 30 shots cos it was shooting so well.... 6.17fps over 30 shot string. I didn't want to ruin it by shooting more... ...that set me up mentally confident.
