Reloading 3" shotgun shells

[king]

Has anyone reloaded a heavy 3" load? I have a ponsess-warren reloader and have several different 2 3/4 loads but I am having a hard time getting the right wad/shell combination. The powder always leaks past the wad. Any information would be appreciated. Preferrably a 1 1/2 oz or heavier load

Lot's of good loads out there.  Here's one:

I've never had any problems with remington hulls & wads.

I suggest the loading manual from Ballistic Products, covers every kind of load you could want.
