FX bobcat MK2 in.25 cal

Jump to latest Follow Reply
Original Smooth Twist barrels were designed around JSB pellets, WAY before slugs were the "thing". That's not a bad thing as they're some of the BEST pellet barrels ever! Smooth Twist & Smooth Twist X barrels came after. There are a few guys who've claimed their OST guns shoot slugs OK but NONE of my OST guns (Bobcat .22, Royale .25, Boss .30) shoot 'em worth a damn. Save your money trying IMHO. Either JSB or FX 25.39 or 33.95gr are the best choice for your gun. Should have no problems getting out to 100 yards +. My 1st Kill ever with my .22 Bobcat was a head shot @ 102 yards so, there you go. Your .25 can definitely do it.

But i don't understand that why the fps has no veriation even when the filling guage goes to 160 and 150 bar.

If your supply drop to 160b and 150b, and your reg psg reads 210 after you have shot several shots, I would assume your reg gauge is bad. The reg pressure can't be higher than the supply (tank, tube) pressure especially after you take several shots as I described above.

You can fill your supply tube to 200b and shoot it down until you see a drop off in velocity, assuming you have a chrony to monitor the pellet velocity. Where supply pressure drops in velocity will be a close approximation of what the reg psg (bar) is set. Hope this helps.

Get some JSB 33.95s, my Mk2 likes them best...I never adjusted my hammer spring much and mine shoots 33s at 775...and does fine at 100 yds...I shoot 25gr on low power mostly. I think 800 to 825 would be easy with the 33s with slight HS adjustment if necessary....I don't mess with mine...I would ignore the reg gauge and just shoot some 33s and see how they work and check your shot count think mine was around 90 out of the box on high. The Bobcat is an EXCELLENT airgun...good luck!
