I'm on my 2nd HW110 both purchased 2nd hand.
The first one I had the first owner had been back to the selling RFD who then sent it back to HC as it was under power.
It was supplied to me with a chrono string printout after HC increased the power this was from the RFD that originally supplied the rifle.
My 2nd HW110 coincidentally is also supplied by the same RFD there's no print out this time but when I checked it over my clubs chrono it's putting out 11.3 so no issues there.
Plenty of manufactures have put out slightly lower power on newly released models.
I remember a few years ago when the AA S510 were first released plenty were moaning about lowish power output out of the box.
Knightrider if your thinking of buying a new HW110 simple answer is just get the RFD to put it over the chrono for you at point of sale
