If you have a rifle chambered in 458 LOTT, can you also shoot 458 win mag ammo in it as well....? They are both headspace off the belt so my guess is you can. Say your ammo does not show up and Lott ammo is not readily available would this be fine to shoot with a scope adjustment of course. Also would prolonged shooting of the shorter cartridge do any harm to the chamber. If a person was trying to condition themselves to recoil by starting with 458 Win Mag loads and working up to Full 458 Lott loads? I must assume if you do shoot the win mag in the lott you will loose velocity just as you would shooting a 375 H&H round in a 375 Ackley or 375 Wetherby.
Any input is appreciated.
