What exactly is the"remarkable difference" between a .458 Lot and a .458 Win?
And what are the experiences, that you will never use a.458 Win on boffalo or Elefant?
The case capacity is too small to push 500/550 grn bullets at an acceptable velocity without getting into pressure problems.
I have on 2 different occasions had clients rifles lock up after the shot, with the client not being able to cycle the bolt! The reason for this is that due to minimal case capacity, rounds are often loaded to max. This is fine when you have cool weather but when it gets hot in the Zambezi valley or KZN, the extra heat causes the spike in pressure and lock ups.
I have also seen penetration issues with this cartridge due to the lack of MV.
Now if you cannot reload your rifle after the first shot, you better hope whatever you shot at goes the other way because you now only have a club in your hands.
The LOTT on the other hand achieve respectable velocity with the same bullets without the pressure issues.
I will not use either myself as the are both straight walled cases and have belted cases.
I use a 500 JEFF and that has a bottle neck case, no belt, no case capacity issues and fires it's 570 gr bullet at low pressure to 2300 fps which is more than I need for any situation.
