I know majority of us had problems with tench, i still have it in my .22 r10. I wanted an increase in fps. So, removed the bottle turned the regulator cw half of a quarter and now regulator is not holding pressure anymore. It was leaking from breath holes. I was at 800 fps for jsb 18s, wanted 850. I know it can go to 820, BUT is that a limit, or trench can go further.

Tuning Tench Regulator, BSA R10 SE

Order the huma reg for the r10. Best choice for the R10 in my opinion. They are very consistent once its settles down. I have it on my r10 and its worth every peny.

Take a look at the Robert Lane bottle reg as well. Excellent build quality at a good price.
Another good quality option is Altaros.

Have you tried maxing the reg (till that highest whatever no leak pressure) and crank the hammer spring?

No i didn't cranked the regulator nor the hammer spring to max. I increased the reg a bit, but it didn't hold the air. Tried to stop air but after 100 bars valve was also not holding the air - no more air in the bottle now. And now compressor is not able to fill it. Tried loading the gun also.

That time i finished installing 350cc cf and was hoping a little high fps with good shot count. But the reg and then the valve didn't wanted me to enjoy it. Now i m back to office and will work on it during weekend. Meanwhile will be looking for suggestions.
Thanks

Hi Odoyle
I finally fixed it. Regulator block orings were also charged. Then started turning. I cranked the reg to max and the loose it one full turn. Also adjusted the HST. Fired 20 shots over chrony and with es of 7 my avg was 855 fps. I also tracked the air consumption. And after each 5 shots avg consumption was 1.4 bar/shot. Pretty good..
Then i played with scope mounting, leveling and zeroing - took an hour. Meanwhile sun set was a few minutes away and temperature also dropped.. i fired 3 more pellets and they at 838, 842 and 845 fps. Reg was at 155. This got me worried. Cause if reg goes off at 155 bar i will have less shots. I was expecting 70 shots. Maths of current setting says you will get about 55 shots.
The question is could be low light over chrony, lower temperate or do i have to do adjustments to reg and hst.?
