Don't have a favourite, haven't owned enough to qualify as having an informed opinion!

However, I did like my 500 3 1/4" NE but kept the 500/450 3 1/4" Magnum as it was, I felt, more useful, and it has a set of 375Flanged Mag barrels. Some days I want to kick myself....

I did like the 404 Jeffery I had 30yrs ago, don't know why I don't have one now. The 450/400 3" is nice too, but mine was a single.

Like Postman, I think they are all great. Especially with modern powder and projectiles.

I think it comes down to finding one (or some!) in a rifle you really like, that fits you and you enjoy loading and shooting it.
