Need to do some homework, on ocassion you will find a gun that just doesnt shoot well but they are rare! First make sure your rifle is consistant, check with a chronograph, id your shots are more than 10 fps apart a tuneup is in order. Id it is consistant then look carefully at your barrel, mabey even push some pellets thru and look them over closely!! Mabey some barrel lapping might ve in order and also check the crown. I have worked on rifles that do not group consistantly and found a good recrown fixed the issue. Check the screws holding the action in the stock, pressure on these mounting spots can be critical. From my tuning days the HW77 was always picky about stock screw tension... And...remember not all tins of pellets are the same, even though they should be....only way to know for sure is to buy lot numbered pellets so all in the lot came from same die, or they are supposed to anyway.... Most times these accuracy issues can be solved, but it may take time and lots of homework!!! As nice a rifle as the 77 is, it can be very hold sensative. I shot one in competition for a year, I did well with it, but found it to be very hold sensative, so much so that I moved to a TX200 which I found to be less hold sensative. The HW77 is a great rifle, well made, but can be quite picky when it comes to pellets, hold, and stock screw tention. With some serious evaluation and patience, I am sure you can figure it out. Good luck!
