it should have a max pressure stamp on the block or near the barrel.
i do not own one, but all pcp's should have a stamp with the info you need on them somewhere.
I think this may be in the wrong section but again there has got to be one o here that can help me.
What is the correct fill pressure to be used in a BSA Ultra single shot.
Thanks

I have a BSA ultra single shot in 177 and if you fill it to 190 bar you should get about 30 good shots with not much change in fps. Hope this helps

MAD FOR IT
...I am not sure but i wouldn't take it that high, unless you are really sure!...(Not trying to offend)
might be best to ask bsa?....i never fill my rifles to the 'maximum' fill pressure stated on the action!
Firstly, they don't normally perform at their optimum power curve untill a fair bit down.
Secondly, i see that pressure as an absolute maximum....I could be wrong of course, i just felt i had to give my opinion.
Goodluck,
Mike.

fill pressure for ultra best place i found to look is
http://www.bsaguns.co.uk/PDFS/BSA%20Ultra.pdf
for .177, its 232 bar, and for .22 its 200 bar max pressures.
these bottles are normally tested to 1.5 times there working pressure.
i agree with black scale though about power curve and peak performance, however i always fill to 10 bar less than recommended so i can eye in the scope with a few practice shots before going for kill shots.
