can't find it!

[R.I.T.Z]

okay a few months back a member posted a link to a very helpful fps calculator, let me finish before you go on posting links.
i have searched asc meticulously and cannot find it and have tried googling it.

now what i mean by the calculator.
it had two sections you put in the fps and bb weight on one side and then selected another bb weight and it would give you the estimated fps with that bb so example

300fps 350fps
.2gr = .25gr
(example not real math)

so if some one could possibly help me find this damn thing it would be great i will continue to search
