top hat
on all the pics of the top hat in the quick ref section it looks like to me we are seeing more like .250 gap between the top hat and valve . am i seeing things or was this done on purpose to clarfy things a bit??

Is it okay to adjust the TH that low? I was under the impression, that it was not healthy for the gun?
i only have 15 grain pellets right now so i was trying to turn this sucker down. I only shot about 15 times at this setting,,This was slower than i wanted
——————————————————————————–
MY top hat ‘s original setting was .095
My accuracy was not good over 900 with rws super domes,or hollow points ,the rws match meister’s were better up to 1000 but they even shot tighter at 900 .
Gamo Hunters shoot one hole at 850 to 900 and up to 975fps 1/2 ” along with the rws meisters match.ALL this at 25 yards.
When i first adjusted to hat down to see if i could turn down the velocity it was at .026 with 1200 psi witch i think is the top velocity for the tank pressure. and i shot 468,468,468,468,470.
Accuracy was one hole at these low velocity with the RWS super domes.
They will shoot 1/2″ at higher velocity but with flyers.
I then filled back to 1200 adjusted TP to .030 and vel. went to 644,641,663.659,this seems very consistent but i did not shoot more than these shots at these settings.
Filled to 2000 and same .030 TP velocity went to740.743.743
Filled to 2500 and same .030TP velocity was 820.818
FIlled to 2700 TP at .035 shot a string 890.893.907.848.913.924.929.930.938.948.932.940.957.972.974.979.958.963.993.990.983.984.983.988.997.990.978.942.992.966.959.955.947.990.940.940.938.931
This is still going in the high 900’s before coming back down and the light pellets will not shoot very well above 910.
So i started lowering fill pressure ,1200 to 1300 is where i am right now with the RWS super dome and Hollow points.velocity is low 900s going down to the 800s , i have shot around 50 times before the velocity went below 700
But i get a good 25 shots in the 800s which is the sweet spot for these light pellets.
I am trying to get the bell curve to start in the 850s go to no higher than 910 before coming back down ,but i havent gotten this yet.
i can’t get mine to go below 0.075″…right now it’s set at 0.093″
thanks , powderburner how many shots were u getting?per fill
i adjusted my condor down to .025 and 1200 fill ,shooting 15 grain pellets it was consistent as hell, 468fps. Just playin around .

The risk is that the back of the tophat contacts the brass brass of the valve body at the front of the tank.
I would guess that the more this peens itself against the other metal the th threads could be deformed or the valve stem itself could wear a bad groove in the delrin seals… 😕
I like a small th gap but do not like the th slapping on the valve body…
