Hi,
My FX Bobcat Mk2 in .25 used to shoot the JSB Exact Kings at 860 on max, 620 on mid and 465 on low power, and the JSB Exact King Heavies Mk2 at 760/530/370.
Suddenly, for no apparent reason, my FPS dropped to 750/580 and 440 (JSB Exact King) and 640/490 and 360 with the JSB Exact King Heavies Mk2!?
I did not change anything, so I have no idea what caused this...
Any ideas???
I would like to poing out that my FX Bobcat Mk2 used to shoot the Air Arms Diabolo Field 25.4 Grains, Domed pellets at 930 fps/full power, and 650 fps/low power. I then sent the gun to FX Airguns USA for a 'service'. While it was there, I asked Ernest to give me a little more shot count, and he did. He also installed a 3-way power switch, instead of the 2-way one. That is why I have three power settings. : )
On the "score card", when testing the gun, he wrote 900 fps with the JSB Exact Kings. Funny enough, when I got the gun back, I was only able to clock the pellets at 860??? Could it have something to do with me being at 2200 meters? Could that be the reason he was getting 900 fps and I only got 860???
Anyhow. That was then. Now my max power setting dropped by 100 fps overnight...
Why?
Thanks,
Kmd
