My Son has purchased an AT44-10 , it was highly recommended by a Friend, went for the .22 option as he is using it mainly for hunting also the choice of a ABS stock meant it would be robust and would not mark like a wooden stock, also decided on the side lever loading style. Hatsan offer a lot of options with these guns.
features of the rifle :-
10- shot, manual loading, side lever action, pre-charged pneumatic (PCP) air rifle
Precision rifled choked barrel for accuracy, ½ UNF threaded muzzle & fitted muzzle cap
Elevation & fit angle adjustable rubber butt pad
Detachable 10-shot rotary magazine
Detachable air cylinder tube (180 cc) enabling to use spare air cylinders
Built-in pressure gauge on the air cylinder to monitor the cylinder pressure
Standard quick-fill nozzle & air cylinder discharging cap supplied in the box
Dovetail groove receiver for both 11 mm and 22 mm scope mounts
Overall blued finish, black anodized receiver
Resettable Manual & Automatic Safety
"Anti-double pellet feed" mechanism preventing more than one pellet loading into barrel
Adjustable rear & front sight with Truglo fiber optics
2-stage adjustable match trigger for trigger travel and trigger pull force
Gold plated metal trigger & metal trigger guard
Currently getting about 80 shots per fill.
Gun is very accurate , robust and feels good to shoot , weight is good and its well balanced.
Best features are the 10 shot mag ( you get 2 ) and you cannot double load by accident
