Just had my model D in the garden for the first time in 6 weeks plus........now this gun at 6 yards, put pellet on pellet, and I locked the aperture slide at a dead 6 yards (second zero at 25 yards) with the point of impact being the tip of the foresight plus a gnats airspace.
So tonight.........even after 50-60 shots to settle down, it is constantly shooting 10mm high at 6 yards.....Any ideas please??????
Being an ex 1970's two stoke rider...I know the cold air makes a big difference in power to an engine
......(frosty morning + 500 triple kawasaki = pain)........But will it being 10 degrees today whilst shooting, instead of the mid twentys as when it was zero'd make a difference to my old BSA??....Or am I just going bonkers???
Same pellets used (H+N FTT).......and same batch,
Same hold/rest used
Gun was not oiled before storage
Sights still on scribelines.....i.e. have not moved
HELP!
