The redding and forsters are my go too, forste rlately more so just to save 40 bucks.
Whidden etc are up there with them as great dies.
Hornady dies are fine but I dont like that they have a more universal seater but I have several and other than 300bo being to short to work in a coax as I see it properly they work just fine.
I dont really like the windown in the rcbs seater but plenty of people like em.
They are all great products, unless you are after a certain feature such as bushings or special expander balls or something custom then they are all pretty much the same.
