- Matt's Country - Episode 34 Barrel Droop - asking for a friend
The HW80 barrel is aiming too low at all ranges. The barrel is clearly not aiming parallel to the cylinder and there are many reasons that might be the case. We have Barrel Droop and need Air Rifle Droop Compensation.
Having tried a Hawke Droop Compensator which is an adjustable 3/8" Dovetail Weaver Rail with 100 MOA Elevation, I frankly failed to fit it properly. So maybe it's old school time. Camera film? Tin Foil?

Second recommendation for "Get a one piece mount with lock pin and shim with foil" I have had similar problems and found that I needed not just 1 shim of a coke can but 2 under the rear mount to sort out the problem. Remember you are trying to best equalise the adjustment range of windage and elevation turret adjustments whilst making POI equal POA
Seems the simplest way. Wonder how much shim it might need
Recently been researching this issue (no expert) but i came across the 1 piece sports match hop19c mount, pre compensated for barrel droop. Has an arrestor pin also.
I shimmed my fastmount with a bit of margarine lid. Make sure pin into gun. Fixed my hw 80 with hawke.
You can check the accuracy of the mounts by reversing then.
To check the barrel lock, lightly tap down the barrel on your bag after loading.
I had this on a 98 and the problem was the barrel catch was very stiff, reamed out with wet'n'dry then relubed fixed it.
that's a very interesting idea... thank you.
The easiest option is to just shim the scope, you can mess around forever with mounts but the simplest option is often the best way to go.
there is no scope manufacturer on the world who will approve shimming, because it wil bend a scope
Shims are an option, so thank you for your suggestion
i agree that shims are misaligning the tube at one end. But it's a tiny amount and I have achieved it previously. It's always been a debate point to be honest.
@@mattscountry363 the optics tube inside thats used for windage and elevation is bend ,and that wil cause larger groups and wear on the parts inside , i have only fac springers up to the 135 .30 . i use only strong clear picture simple scopes 4x32 , those will hold longer . i think fac springers are more sensitve on the parallel barrel and strong mounting. . and how smaller the objectif lens is how less the parallax problem is .
Get a one piece mount with lock pin and shim with foil
If shimming works for a dozen shots on these cheap-arse 2 piece mounts, then I will get a 1 piece as it's a springer
I use a thin bit of rubber from a bike inner tube Matt, worked fine
Excellent idea Danny. Thanks buddy :)
I've had the same problem with an 80 and a 35. I used the '1 piece' Sports Match adjustable mount on both, and they work brilliantly. They are robustly engineered and although expensive almost certainly the best adjustable's available. I've also used the Sports Match 2 piece, but in my opinion they are a bit of a faf to set up. I've also used the BKL adjustables, but wouldn't recommend them ......... shame because their fixed 1 piece self centering fixed mounts are brilliant. I hope this helps. BTW, shimming mounts can cause tube distortion. Keep up the great work
Thanks Steve.....will add the Sportmatch to the list of potential fixes. My only issue with that brand, previously always my firm favourite, is that recently the alloy has gone a bit soft on some and been very sub par.
@@mattscountry363 Hi Matt... those last SM adjustable mounts were bought approx 10 or so years ago - and still perfect. I bought a single piece 30mm SM mount last week for a 99s and it appeared ok - it certainly stayed ok for the 200 pellets I put thru the 99 to help 'run it in' after some major 'transplant' work Ive undertaken on it. Its sad to hear of your less than perfect experience that you've had however. Please be aware that any shimming can run the risk of tube distortion to some extent. Good luck.
The first step to solving the problem is to accurately determine what the problem is. Is the barrel bent?( look down it). Is the lock mechanism not engaging fully ( lay straight edges on barrel and scope rails and confirm that they are parallel). Once problem defined then solution will be apparent.
Paul... I am gonna do this. I am going to get an inclinometer and see if the cylinder and the barrel are parallel
i try again its not loaded up first time , the only way if there is no play or bent barrel , is by using a file at the white spots where the breech block hits the cilinder , and check constant remove the seal first to see where it hits metal on metal use a marker to make the white spots black / it wil ,make the gun more accurat because the recoil is parallel with the barrel
shiming is bad it wil bend the scope.
a strong one piece mount is the best used on a springer , there is no free movement between the rings
Thanks for not giving up on the reply. Grateful. So I need to degrease the barrel block to cylinder face, mark it up with pen and then close it a few times to see where it strikes and if it's equal?
@@mattscountry363 file the white spots till the barrel is parallel . i use a gun vice and bubble levels , just little needed
I was gonna say try a shim, seems simplest and quikest?
Could the barrel be bent, it is a bteak barrel and wouldnt be unheatd if I suppose?
This is a potential. But having looked it it from all ways, and held a reasonably good straight edge to it.. I don't think it is
