Q:

having a problem with tank dump.

I recently put my .22 barrel back in my rifle to save teh .25 pellets i have im using the factory 80g hammer and havent moved my tophat the problem i am having is that i only get 1 or 2 shots then my tank dumps but it doesnt do this with my .25 barrel if someone who still has thier tank at factory settings could please let me know what theyre tank is set at from the brass to the bottom of the tophat i would greatly appreciate it. i called air force this morning and they told me they are typically set somewhere around .090 mine is at .116. not sure if this is a QC problem of if maybe the tophat has just moved. any info you can provide would be greatly appreciated.

Hi
I had several tank dumps and i noticed that it happens every time i lube my handpump . The first time the tank dumped was when i shot too much(about 60 ) pellets , (then i thought so ) . The second time i shot 5 -6 at PW 10 and fill presure 2700 . now i pump with completely dry handpump and there are no problems . I don’t know whether the reason for dumping my tank is lubing my handpump .
I shoot my condor absolutely dry because when i lube it , it starts shooting strange . I stopped lubing my pellets ( baracuda extra heavy ) and the rifle become more accurate . I guess this will cause leading the barrel and will ruin the seals of the handpump (it is very hard to pump when unlubed ) .
Condor is great rifle( like no other ) but it seams it needs special care .
P.S. Please excuse me for my english . Im from the Balkans 🙂

I was guessing after i checked the tophat setting on my buddies brand new condor and it was the same as mine, i had to second guess everything. i dont totally understand the tank dump or i wouldnt have been here asking what others thought could be wrong i was making stabs in the dark.

i figured out the problem. it was lead dust oming back from my shroud and past the bushings somehow i completely disassembled it cleaned everything out put it back together put a little silicone lube on the bolt where it rides on the barrel and no more problems.

“i have no clue how it happened but after i cleaned it all out no more tank dump.”

I wondered if you actually understood the tank dump 🙂
sounds like you are guessing?

Walter…

i have no clue how it happened but after i cleaned it all out no more tank dump.

How did lead dust cause a tank dump?

if you don’t have a crony to fine tune it just set it flush with the threads on the stem.

My Hi Flo tank was set at .125 or 1/8 ” Factory. Now use .109 or 7/64 😕

its all factory i think ill try 90 and see what happens. thanks.

.90 is about right I think, maybe a little less. (.87-ish)

.116 is way too high, unless you’ve got some sort of heavy-duty mods going on.

start at 0.070″ see if that solves it
