Depends. If you count the individual rifles I have owned twice, or that passed through briefly, about 9 or 10.
Aside from a Brazilian Mauser, a memento of an old friend, all my rifles are old tang safety M77s from 70s-early 80s. Each has the identical stock profile from before they changed it. I cut them all down to my smaller size and replaced each pencil eraser butt pad with a grindable Limbsaver (much nicer on the magnums). For me, these just fit right. None of them are pristine collectors’ items, far from it.
