Welcome to the Fire. I want to make sure I am correctly interpreting your original post, because it seems like there is such an obvious question, which nobody has asked you, that I fear I may have missed something.
That said, as I read your OP, the rifle now shoots worse than it did before you did the bedding job. It did not shoot GREAT before, but it was not throwing the weird fliers like it is now.
Is this correct?
I think that's important to clearly establish before the respondents can help.

Cheers,
Rex
