I don't think you will find any magic in a 28 using a load that you could use in a .410. 20 or 12, for that matter. It is simply the weight of the load and the velocity at the muzzle that effects recoil. And the weight of the gun affects felt recoil.

The heaviest gun, shooting the lightest load, at the slowest viable velocity will have the least felt recoil. Gauge is pretty much irrelevant.
