Just received my first PCP. Brocock Contour S6 Elite. 22

I received my Hill MK4 hand pump and JSB pellets yesterday. I just finished running 3 different .22 pellets through the chrony with all starting at a 200 Bar fill. H&N FTT 14.66gr., JSB Exact 15.89gr., and JSB Exact Heavy 18.13gr. I will run them through the chrony at a lower fill, maybe 185 to 190 Bar. Here's the results to include my cheesy graph lol. If anyone has any suggestions, I appreciate your input and advice.

H&N FTT 14.66gr.

Peskadot671 looking at your various shot strings you need to determine what extreme spread in fps is acceptable for you. For example looking at the JSB Exact say take shot #5 thru #25 and you have an extreme spread of about 29 fps which would be acceptable for me. So then fill you rifle again to 200 bar and start shooting over the chronograph. When you get about 685 fps note your bar fill level and that will be what you initially fill you rifle to. It might be about 190 bar lets say. Looks like you should get about 20 accurate shots per fill. IMO Bill
 
Thanks for the advice Bill. Like I said earlier, this is my first PCP. I was thinking of shooting off the first few shots but I didn't know that you could just fill to your desired pressure after confirming the extreme spread you want. I'm glad the gauge on my rifle and Hill pump are the same. Thanks again for the tip. Gonna try it out and report back.
 
I have a Daystate Regal XL and a Brocock Concept Elite S6.
It very close to the Daystate 25 foot pounds vs 30 on the Daystate.

I think its confusing with Brococks naming. Countour, Concept, Elite, non elite, S6.

The countour looks very much like the E S6 but it has a cut out in the stock (Lighter) and the E s6 has larger air tank and 25ft pounds.

Shots I get 40+ from the Concept Elite S6, in its price range nothing is better.
