Best advice is start with the Handi Basics 101 sticky, then spend some time in the FAQs and Help sticky, pretty much everything you want to know is in there.
My 444 shot the 265gr LE ammo into 1½" before it was in the box at the factory, it was one of the first, if not the first 1:20" 444 made in 2007, shoots handloads excellent.
