RE: 458 Lott from a .458 Winchester?
Welllll, I' m so very happy to know that I' m not alone in wanting one of those big doubles and unwilling to shell out the sheckels to own one.
I happen to own a few machine tools and am a former tool and die maker and now have a book entitled " Making Double Rifles on Shotgun Actions"
Several years ago I made a double .30-30 on a Brazillian action. I was proud of it but it was a first and not as accurate as it should be.
There ain' t a big bull elephant on the planet for everyone that wants one, that' s what makes them so valuable.
I' m one lucky SOB to have done a plains game hunt.....and have a few African trophys. (used a .300 H&H that I customized)
