Ramrod, I agree all the way. I've had a couple .458's- a 2" and the normal 2 1/2", but the one I liked the best was the .458 Alaskan, my own version of the .450 Alaskan - a blown out .348 with the rim turned down to .532"(magnum bolt face) and with a new extractor groove done in a single cut - a 30 second job including insertion and removal from the lathe. Once need only grind his cutter appropriately. With the TSX bullets, feeding was perfect in a M70 that used to be a .264Win Mag. The factory magazine held 4 with one in the chamber.

This one has just a tich more capacity than the straight .458 Win Mag so I was able to make 2,200fps with 500gr. bullets quite easily. Being bottle necked helps with the slight compression with appropriate powders.
