Ed's into game bird survey and population management also I see.

Should you hand load 20's, Alliant shows a one ounce load using the AA hull, 20/28, and the RXP20 wad.

I shave a grain and a half off what they publish and the load runs 1130 fps which puts it at about 20 FP free recoil on Drew's chart there.

I can't tell it from a factory skeet load recoil wise.

The idea of 1 oz. in a 20 is for density, and lower velocity helps to keep the fliers down. Manages recoil too. Winner, winner.
