I have also found the cheap winchester walmart value pack buckshot to pattern nicely out of the weapon.

I do have some of the new federal tactical #1 Buck I need to get out and pattern . . .
I have a lot of the PDX1 myself, and it's great for short range (15-20 yards Max) as you mention. I have however found that the Centurion buck and ball is more accurate (the ball) a little further out. Not that it matters for HD, and with that said I prefer buckshot (preferably plated, but I have no problems with cheap Remington value pack 00 buck either).
