At last i got out today with the hw100 after its been in the shop, they said it was doing a steady 11.5ftlb so i didnt bother checking it, i had the new scope on aswell so went to a farm and got it zero'd at 30 mtrs and set off for a wonder, it was a bit windy so didnt take any long shots, got 4 ferrals at about zero range (2 left on roof for the kite) , it didnt feel right to me so just got in and crono'd it and its doing between 10.8 and 11ftlb, not going any higher than 11, il google it and see if i can adjust power, is it easy.
