I have just had ocassion to dig out an old G&A article about Jacques Lott. In 1971 they ran a piece about Tom Siatos and Jacques Lott developing what they said was the very best 45 cal rifle cartridge and it was the 460 G&A, a 458 on the 404 Jeffery case. One up and three down Jacques considered it the best for all manner of reasons and I think he later went with the what we now call the Lott was the prolifferation of 458 win rifles that could be re-chambered. He did look at the full length 458 Ackerly Magnum but wanted to do away with the belt and decided the 404 case offered the best combinations of desirable characteristics.

Wasn't the primary advantage of the .460 G&A the ability to clean up the chamber of a .458 built on a non-magnum action?

Sorry, I was thinking of the .450 G&A.
