Is this convesion doable? Difficult? Thanks "D"

D Hunter, I am not an expert on this matter, but yes, I think it is possible, depending on what action you use (magazine length may be a factor in some bolt actions).

Everybody talks about the 458 Lott, but I would consider the 450 Watts instead, then you can shoot all three in a pinch.

I do not now much but the other guy's on this forum reckon it is just a matter of running a .458 lott reamer I think up the barrel and thats it (correct me if I am wrong). You could just get a second hand 602 in .458 win mag or buy a new cz 550 in .458 win mag and that should work out really well, you will be able to shoot .458 lott and in a pinch also shoot .458 win mag ammo.

One day I would like to own a .458 big bore and I think I will go with the .450 Rigby to match my .416 Rigby. I would love a .350 Rigby as well.
Regards PC.

From what I have heard, the chamber work is no big deal, but getting it to feed correctly might be. Your particular rifle may not be set up to handle the cartridge OAL of the Lott in the magazine.

I know a lot of people here have done it; you may want to include specific information on your rifle, to make answering the question easier.
