My .177 Scorpion se has the larger 325mm cylinder fitted and a regulator.
From 200 bar down to 100 bar i'm getting 120-130 shots. I'd get more if I took it down to the pressure the regulator is set at but with that shot count ive no need.

*edit*
I got around the silencer issue by fitting a 27mm shroud with built in air stripper. Its even quieter than before when I had the HW silencer on it.
