If you can find two loads they you can see which pattern well and go from there. I also expect there is a Federal 20 load out there to try.

I did some of this as well for 12 gauge, but it is easy to get powder migration above the sealing cup when loading wads meant for tapered hulls in straight-walled hulls, and Longshot is fairly small grained, so it does this pretty easily. The low pressures for these loads depend on a fair bit of blowby caused by the hull/wad mismatch. Shotgunworld's reloading forum sees this discussion over and over.
