Paul,
I've been loading some 12 gauge 0.5 and 0.6 ounce loads for about a year using Alliant Extra Lite powder. Work and sound fine for close in targets.
I sent some samples of these loads to Tom Armbrust for testing and they are all under 5500 psi with the velocities around 1300 fps. I used Win AA and Rem Gun Club hulls, about 14.0 grains of EL powder, Rem and Win primers and CB 0175-12 3/4 ounce pink wads. I used 20 gauge card wads of 0.070" and 0.125" thickness to take up space in the bottom of the wad.
This morning I FedEx'ed Ground two sets of similar 12 gauge loads to Tom for testing: 0.5 ounce using EL and 0.6 ounce using 700X.
Probably be a couple weeks before I get results but will be happy to share that data with you or anyone else that's interested.
Bill
