Having known for years that all my unaltered .458 WinMags on the .30-06-length actions will eject unfired cartridges up to 3.54"
I never even thought about using a .30-06-length action with shortened ejector-bolt-stop and lengthened box
for a .458 WM+ and 3.6" COL.
Let me add to this, as I stated previously on the .458 thread that I converted a Model 70 .458 Super Grade to .416 Remington with the magazine changed out to accommodate longer cartridges by having a 95mm internal OAL capacity fitted and even those longer than factory spec cartridges loaded and ejected fine with no changes to the action opening whatsoever so, as Ron has stated, the .458/.30/06 action was left intact. It is not complicated and it is reliable, which is the main objective with dangerous game cartridges.
