Twelve Bore
Welcome back Kotter (stolen famous TV Line). Recoil, or lack there of, is more a product of the weight of the payload (bullet).
So, to begin your search for a "Hand Saver" start first with a light bullet that carries a boat load of BP Lube. The .44 "Slim" and .44 "Mini Mav" are right in your wheel house at 180Gr or less. Then look to your "load."
Your choice of Breakfast Food for filler is spot on. Cream of Wheat does not compress and burns completely and so serves as an excellent filler. My suggestion for load would be 15 - 16Gr weight of BP with the C-0-W providing the compression.
Should be an absolute pusseykat.
