Thread: Down loading 243 win to 6x45 velocities

This is really interesting, I was thinking about a 6x45 but after a bit of thought I was pondering downloading a 243 might be simpler than custom building something the kids will probably grow out of pretty quickly.
Is it normal to get good accuracy when downloading or have you just struck it lucky, I thought I had read that by downloading pressure and velocity were kind of random and accuracy opened up, but that also may have been when using case fillers etc.
