Tuning TX200HC with barrel droop?

[jschwartzlow]

I have a TX200HC that seems to have a considerable amount of barrel droop (beyond scope adjustment). I don't expect an underlever in general or a TX specifically to have barrel droop. The rifle is otherwise quite consistently accurate. Is there anything I can check which may have broken or be out of alignment?

Nope even fixed barrel airguns in fact most have barrel droop. Either bend the barrel up or use droop compensating mounts.

At one point and even now I was mostly 100% using adjustable mounts and moa bases on everything so I can at least optically center my scopes and don't need to lap the rings which probably most don't even bother to do that can damage and put undue stress on their scope tubes even without shimming. Noticeable damage are evident with ring marks you know it was possibly shimmed or rings weren't lapped even expensive rings can cause this believe it or not.

You can also have unseen scope damage too without any marks and you will notice that the zoom ring and or parallax focus is extra stiff and or elevation and windage turrets don't work as perfectly as they should after mounting your unlapped non adjustable or rings that you used shims to boost the rear up.

Whenever buying a used scope always always always ask if the original owner properly lapped his rings and never shimmed his scope and never on a Springer or gas ram or magnum powder burner before buying it especially if it no longer has a lifetime warranty to the second owner after doing your due diligence what brands to avoid buying used due to no warranty for the next owner.

The other alternative is to use a low magnification scope that way you have more elevation to play with to compensate for barrel droop. Like a 4x or 2-7x or maybe a 3-9x.

Losen the barrel nut in the breach and turn the barrel 90 degree.OK if barrel droop is down?turn barrel opposite way ?up. Yep 180 im lear'en"

Loosen the barrel nut in the breach and turn the barrel 90 degree.

90° is one quarter turn.

Don't You mean 180°?

Since 360° is one full turn?

90° is like the hands at 3 o clock

While 

180° is like 6 o clock

Just purchase a Diana or RWS lockdown one piece mount with droop compensation. Inexpensive and permanent fix. Have on all of my underlever rifles.

☝ $9.99 at UmarexUSA with possibly another 15% off if the discount code still works.

Thanks. Not what expected, but good to know this is common in underlevers too. I did have the RWS mount laying around and currently have it on the rifle. It is a bit high, but corrects for the droop. Now if I can just find a fix for the safety that doesn't always reset.... There used to be an aftermarket parts, but I guess it isn't for sale currently.

I'm curious if I can lossen barrel nut and turn. I may try that someday.

Thanks,

John

First do 2 things out some sewing machine oil or 3 in 1 oil on the safety switch let it go in and cock it with a firm tug at the end of the stroke many times like going beyond bottoming the cocking lever.
