The difference between go gauge (tight fit) and a filed reject I believe is about .010.

That is almost infinitesimals (I had to look that one up!) brass growth, you can get by far more powder in a case by going to the lighter Hornady brass, Nossler I think as well. That is trim length (and the trim is at the neck)

As far as bullet jump, .010 is also insignificant . I don't make any less than .005 adjustments as the OGVIVE variation is more than enough to make that a mute point (once can be into the lands and another out of the lands with the variant if you are really close)
