Where do you play? Some of the older FSJ players may or may not have velocity limits. I remember playing against some of them several years ago and their guns were well above 400 fps then.
We don't have specified velocity limits in GP for the most part, but I suspect your gun will not be lasting all that long at 450 fps if it's a version 2 mechbox. The G&Ps we had years ago at that velocity never seemed to last more than 20K rounds at the absolute most anyways.

Freedom is the wolves limping away while the sheep reloads.
Never confuse freedom with democracy.
