Hey Guys,
I am thinking about getting a model 70 458 Win mag and converting it to a 458 Lott, the Lott is a longer cartridge , so would I also have to have the magazine box made longer. Will the Lott chambering shoot the 458 win cartridges as accurately as a standard 458 win would shoot them.
Thanks Guys
 
You should be able to get a 416 rem mag box and bolt stop. I doubt that’s all that will be required to make It feed 100%.
 
Consult a good gunsmith about your rifle. While the barrel work is easy, and the mag work may be doable, the question is whether the action length is sufficient without removing metal (not a question I can answer).
 
Here is a previous thread about it...

Can't you come up with a modern powder that will enable a Win Mag to approach Lott velocities?

For me, It's more about the bullet tip than velocity in big bores. I think the Win Mag will get it done all day long with the right bullets... Just my two cents to save you some money. Good luck what ever way you decide to go.

Do you have any cull hunts available? 7 days, daily rate plus per animal price?

Hi Roklok
I read your post on Caprivi. Congratulations.
I plan to hunt there for buff in 2026 oct.
How was the land, very dry ? But à lot of buffs ?
Thank you / merci
Philippe
