Sir Bevan, Ditto Sir Scotty on the .300 WinMag and PF conversion. I have not done one of those boltstops paired with plunger ejectors but it might even be simpler. All the rest is the same. The .300 WinMag has a leade-only throat, as do the .338 WinMag and .264 WinMag and .458 WinMag. Family trait. That said, I have a Ruger M77 Mk II .300 WinMag that is spooky accurate, no problems with that throat.
