Mine did the latter which may have led to a little loss of gas, but it didn't shoot low like yours. I added some pressure on the detent ball by stretching the spring which is under the rear sight. It is moving 7.0gr pellets at just under 500fps, and is bl00dy loud!

Have you checked the barrel crown for any burrs that could be deflecting the pellets?
Hi Modski66, yes punches clean round holes, using R10 pellets and off a rest groups really well. The bolt stays in place when fired and oh yes, she’s loud. 😂. When first fired, the POI at 10mtrs, from a rest, was to the right about an inch and about 4 inches low. Raised the rear sight and before the adjustment screw was all the way out it’s now 2 inches low. Power appears to be there, groups well, just low.
