I don't want a 460 at all. To much for that short of a barrel, a 454 will do all you can get out of that barrel. I don't think you could gain but maybe 200fps with the 460 in a 6". And wow what a flame.
I know what you are talking about I do love the 445. I was thinking in the 454 you can get cowboy loads for the 45lc and plink but you know in the 445 you can shoot the 44sp. for plinking. And lots of people are going to the 44sp.
