Sorry mate but you are wrong a chronograph does not lie.    Bisley magnums 10.65 = 11.3.  qys 9.56  =11.5 jsb excact 8.44 = 11.8 I altered my power on my fx last week and these were the results, it's no diffrent with a 22

I should say that over distance then yes the heavey pellet does hold its energy but not at the barrel, and that why lighter pellets could put you over the 12lfb

Heavier pellets have ALWAYS increased the fpe when ever i have used them in sub 12 rifles. It is not uncommon for Daystate rifles to be low on power but for GOD'S sake, do not sent it to Daystate to h

Try some lighter pellets mate it should bring that flb and the fps up, the first shot is ok on power but the rest are low,  it's ok but I would sooner it be shooting at about 11.5 flb

Average 565.4 fps. 10.7 flb but you are better doing 10 shots

Sorry mate but heavy pellets give you more ftlbs in pcp normally . That is why tuners test with 10.3 gr in .177 and 16 gr .22

That's more like it, what did the heavier pellets give you. The average on that 600.7 fps at 11.7 flb

You have some good guys in your neck of the woods such as our Jimmy, or better known as bigmac97 who may be able to point you in the right direction or send the gun to Ratworks tuning house in Leicester who did a great job on a couple of Daystates for members on here.

Never heard of lighter pellets putting any rifle over the 12fpe limit and in that case why do police test sites keep heavy pellets to carry out checks if an owner doesn't supply their own ???

Those figures might put you over with a different pellet. You need to try different pellets 👍🏻

some weight written out and about for bisley mags are wrong they state a too higher value . also a tighter pellet in the barrel will give different reading its not just weight .

So in theory you could have your rifle at say 11.3flb with your favourite all round pellet and change the pellet for some reason and be over the legal. There are a lot of diffrent pellets on the market varying in weight and how they are made

Police would check with every pellet available to see if it goes over  . 8.44 you should have that running @ 11.3 ish same with 13-14 gr pellet in .22 .

like I said airgun tuners normally set PCP guns up with a heavy pellet , something like JSB 10.3 gr in.177 and AA field 15.9 in .22
