These rifles were designed to do about 10.5ft/lbs or some 550fps, depending upon the pellet. That is what my friend's achieves.
I had an Airsporter a couple of years after my first Mk3 and it was erratic in behaviour. It was no more powerful than the Mk3 and I have read articles where some Airsporters were less powerful. I think we can argue the toss on this.
This is a fascinating discussion.
