I have a 541T that does the same thing. The first " cold " shot is often...not always...but often to the left about 1 1/2" inches. After that things are fine. I don"t know if anything can be done about it. I have heard of this happening with other makes of .22 rimfire as well . I have just learned to live with it in my 541T . I also own a 504 in .22 but it doesn"t throw the first shot.
