Removing the regulator system from a bsa superten

[metalmickey]

I HAVE A BSA SUPERTEN CARBINE .177 CALIBRE SHORT BARREL WITH THE LARGE BSA MODERATOR ON IT. THAT WILL ONLY PRODUCE 8.7 ft lbs M/E WITH 10.65 grn H&N MAGNUMS, THE AIR TUBE / REGULATOR WAS SERVICED BY ROB LANE WHO APPARRENTLY SET THE REGULATOR PRESSURE AT 75 BARS ? ( ALTHOUGH I HAVE NO PAPERWORK TO CONFIRM THIS. AND HIS PHONE NO LONGER RECEIVES WORK RELATED CALLS ) NO MATTER WHAT STRENGTH HAMMER SPRING I FIT TO IT AND WITH MANY VARIATIONS OF DIFFERENT PRE-LOAD SHIMS. IT STILL PRODUCES THE SAME 8.7 ft lbs POWER OUTPUT. I WAS WONDERING IF I REMOVED THE REGULATOR ALTOGETHER FROM THE AIR TUBE WOULD THE GUN WOULD STILL WORK OK ?
AND WOULD IT BE EASIER TO ADJUST THE POWER WITH THE HAMMER SPRING AND SHIMS STRENGTH JUST ACTING ON THE EXHAUST VALVE SYSTEM ?
I WOULD EXPECT TO HAVE THE USUAL SHOT/POWER CURVE INITIALLY AND WHEN THE AIR RESOVOIR PRESSURE RUNS DOWN, THE SAME OF AN UN-REGULATED GUN AS IN MY AA410

TO ALL YOU OTHER PCP TINKERERS WHAT ARE YOUR THOUGHTS ON THIS !!

FAILING THIS I WILL HAVE TO CONCEED AND SUFFER THE COST OF HAVING IT COMPLETELY OVERHAULED BY A PROFESSIONAL AIRGUN SMITH
