Bought a Haenel model 310 BB bolt action repeater couple of years ago , great little gun , low powered but fun , so I am after more info on them , were they designed as a military trainer or fairgrounds use ?
What ammo should be used , is steel ok or big NO (cant see if barrel is rifled or not ) if lead are they 4.4 mm and where can I get ammo to fit ?
What servicing / maintenance do they require other than grease on mainspring and oiled mechanisem is that it , bolt is quite hard to cock is that usual ?
