Is the .458 a double rifle or a bolt rifle?

Also- I want to see photos of that 12bore double rifle!!

Some folks steer clear of double rifles in the .458 as it's not a flanged cartridge, and there is greater chance of extraction/ejection problems.
We have one member here who's taken dozens of elephant with his .458 double rifle with no trouble whatsoever.

Tell is about the .458!
