No idea how much free bore one has, so I'd suggest you do your own research. I have several Weatherby's, and regardless of slug one will never reach the lands. I seated some loads out so far that just running them through the action would induce run out, and some out well past magazine constraints too. I have no issues with that, as I'll shoot in single shot mode if that's what it takes to get the desired accuracy. None of those loads shot worth sh-t. With those cartridges, seating the slugs to at least a caliber deep brought them into the moa realm. I think I'm getting more consistent ignition when the cartridges have a good firm grip on the bullet.
Conversely, one is likely getting consistent pressures when he's bumping the lands.
Have a good one, and do let us know what does and does not work.
