Looks like a few of us has encountered the same problem . I always fire a few off target now then start, I find springers in winter months can have me pulling out my hair !! Great post
My tx200,every 1st shot is a flyer but only that 1st shot.had a conversation with a gunsmith and he told me never ever clean inside barrel of air rifle if its firing well,wish he told me before i cleaned my s400f as its not as accurate before i cleaned it,its starting to group now after 50-60 shots.i used them rods with brushes on the end,nrxt time if theres a next time ill use pull through.
3 shots every time before my TX is on zero.
