I'm seeing the same results here

There is a 20 grain difference between the HP and solids. The solids I managed to recover, which was darn few, got tired of digging, retained 92% of their weight after 4" of damp newsprint and 18" of dirt, the HPs retained an average of 67.5% of the few I managed to dig up, they went through 3" of Jack O'Lantern and close to 14" of loose dirt and rocks. I'm thinking a 355gr Solid, or even a 325-330gr at 12-1400 fps would likely go almost end to end on a cow elk. Everyone, except barrel makers and a few others tell me the 1:24 twist of the FA won't stabilize bullets over 300 grains unless they are pushed over a certain velocity, I know my 325gr WFNGC bullets are still stable at 150 yards when shot at 900-1000 fps, and the barrel twist calculators I use tell me the 355s will be stable down below 800 fps. I really want a good, all around load for this 5 gun, one that I enjoy shooting day in and out. I would shoot mostly the 45-270SAA bullets, but I can't seem to get them to not lead, at 285 grains, they retained 96% after Mr. O'Lantern and 16" of dirt, at that weight, if I could shoot them at 13-1400, they would be a good all around bullet.

Here are the heavyweight remains.
