    Try using JSB Exact Heavies or Daystate Heavies....

    What velocity are you getting?
    You can spend thousands and still miss a barn door or spend just enough and enjoy yourself. If you haven't got the talent to start with a million pound won't fix it. Whippet, Russell, a few bang sticks and a flat cap. http://www.smart-tech1st.co.uk

    Not much to be fair - my main hunting rifle is running around 11.5 with .177 JSB Heavies.
    Zeroed at 35yrds with reticle mapped, it works very well.


    But, if I'm honest, I'd see low 10s with a medium weight pellet as a tad under power - especially for hunting with .177.

    All of the above.

    I maybe sticking my neck out here but a 10 ft.lbs airgun should not be used for hunting beyond 35~40 yards. The gun is under powered so needs sorting out. All those who hunt with sub 12 ft.lbs know that these should be on the higher side of 11 for hunting.

    I had a 110 that was underpowered too by about the same amount .I sold it on in a px the rfd said they would send it back to hull cartridge to sort but as has been previously suggested try jsb heavies .I don't find the trajectory is much more than exacts found the heavies to give a ft lb more in my ultimate sporter .

    I have the same problem with my HW110, 11.14ftlb with .177, JSB Exact 4.52 and 10.99ftlb with JSB Exact heavies 4.52 very odd. I have tried 4.51 and they are even lower. I would like it doing 11.7ftlb with JSB Exact heavies which equates to around 715fps as I also only hunt. Is it only Hull Cartridge that can work on these due to their construction? Although I have been shooting air rifles for 40 years I have no experience of dismantling PCPs.

    Cheers, Phil

    Nothing wrong with the power. That level is fine but you need to do a full test over the fill range because it will be hotter in the middle of the fill.

    It is not as simple as that I am afraid. In my K barrel of HW 100 the Heavies make much more power than the 8.44s but in my 56 cn FSB barrel they are almost at parity with the 8.44s if not a shade lower in energy. I believe the length and type of barrel and the regulator pressure has a lot to do with how pellets behave in a barrel. Have you tried the JSB Exact Express? It might surprise you.

    That's immaterial, a sub 12 rifle must be sub 12 with any & every pellet so you test various pellets for muzzle energy in the same way that you test them for accuracy rather than just chuck anything down the barrel.

    Those two should give higher readings & final energy should be set with whatever's highest which may not be your everyday pellet.

    Would it be grease on the hammer spring, same issue my 100 had? My 110 runs @ 11.4 ft lb. Only shot about 500 pellets through it.
