I have been tuning and playing with my TX200 for a couple years. It shoots well but there is always new and improved parts and advice.
So far I started with a Walnut stock standard length Mark 3.
Scope is Aeon 10-40x56 trajectory retical . I plan to up grade to a sightton soon.
I did some clean up work on the trigger and changed the blade to a Rowan adjustable brass piece.
I am using a vortex 12 ft lb spring.
It shoots 7.87 AA pellets at 800-815 fps.
I also added a hamster and am going to add an adjustable recoil pad
I started shooting with DIFTA in Maryland . I moved to Iowa and not have to drive three hours to Wisconsin to shoot.
i have not had a problem with my scope . The side wheel came loose and I had Todd over the whole side turret to repair it. Three screws under the turret base backed out. I have mostly been at 12 ft lb so it is not a real harsh shot cycle
I don’t have a problem with the spring. I test it often.
Accuracy is better than I can shoot. Five shots from a bench rest at 25 yards is under a dime.
From my seated position I can keep three or four under a dime some of the time . And under a quarter most of the time
Curious about the extra screws located near the breech as seen in the pic above. Did it come that way?
~GOD BLESS~

That is a .177 in bottom of pic tuned with the Vortek 12 ft spring and new seals from Chambers... The other TX is my new .22 and I have not had a chance to work on it yet...
Here is another pic of the .22 showing no "extra" screws at the breech...
Today I was thinking about the piston weight reduction that has been going on. I have a steel top hat in my TX200 my 3 it shoots at 11.3 ft lb. with air arms 8.4 diablo pellets
The hi 789
Low is 765
Average 767
Ex is 24
St D is 8.
The steel top hat weighs 13.4grams . I made a duralin top hat. It is 3.4 grams or ten grams lighter. I made it 3 mm thicker.
With the same Air Arms 8.4 pellets
Hi 817
Low 797
Average 810
Ex is 20
St D is 6
Then I tried out my new JSB premium gold match diablo pellets. 8.4 gr in the black box

St D is just 3
I’m not sure I want to try lightening the piston anymore. That is as good as I have ever gotten.
