I am happy to oblige, please find an extract from an advertising broadsheet for various velocity and energy levels on the new Beaumont air rifle based on the Air Ranger/RWS 500:
.22 - 75 ft/lbs. 30,5gr. Pellet in excess 1050 ft/s. (5,50mm.)
.22 - 90 ft/lbs. 30,5gr. Pellet in excess 1150 ft/s. (5,50mm.)
.22 -100 ft/lbs. 40,0gr. Pellet in excess 1050 ft/s. (5,70mm.)
.25 -130 ft/lbs. 50,0gr. Pellet in excess 1100 ft/s. (6,35mm.)
.25 -120 ft/lbs. 36,0gr. Pellet in excess 1200 ft/s. (6,35mm.)
.30 -175 ft/lbs. 110 gr. Pellet in excess 850 ft/s. (7,80mm.)
I understand that the velocities are the minimum specified for a string of shots where the velocity will increase over the series before falling due to the power curve. Over 1300ft/s has been recorded with 36 grain .25 ammunition.
This gun has been developed for Export markets and for longer range shooting. Accuracies of 25mm groups are acheived at 150 metre ranges. Alfred the gun's developer reports that these accuracies are generally better than achieved by firearms.
