Sir Bob,
That is a great .458 WM+ load. Buy a donkey for that contribution.
Seating depth is about a quarter inch, with a DGX-Bonded 480-grainer.
Might be close to a tight fit in the .458 Lott throat.
If one used the factory cannelure for a .458 Lott the COL would be about 3.500".
Better advise any Lottites to use caution with your excellent .458 WM+ load,
and be happy with their lesser loads for the .458 Lott.
.458 WinMag beats all, in the all-around contest.
