From what i hear mate Falcon keep their rifles well low on power just to stay the right side of the law.
They always make sure it's well under the limit with Bisley magnums.
When i bought my AA S410 k it was 10.5 ft lbs without me knowing & i knocked over plenty of quarry with it,only when it went for a service at Hydrographics did i know & they cranked it up a little so i don't think your power is that low,hope that helps.
